i'm bored so i want to know your opinion of the 911 bombing attack of the twin towers
The attack on 911 is part of a systematic world-wide violent attack against anything that is not Islamic perpetrated by tyrannical and evil jihad-waging radical Muslims.
It is not a doubt for me. Anybody who is ignorant enough to base what they believe on what they are told, rather than what makes sense, knows the truth. Now, a large fraction of the people who know want it to remain a secret, remember that, and remember that they have to somehow fall asleep every night.
83% of polls conducted last year in the US had a majority belief that the government's story behind 911 was incorrect.

Many ground-zero first responders are contracting sarcoidosis, a lung disease, which scientists everywhere claim can be caused by common demolition explosives.

The buildings were evacuated 2 weeks before 911 for a "security inspection"

the number of people WITHIN THE US who bought shares of United Airlines stock that would MAKE MONEY IF THE STOCK WENT DOWN was 32x higher on the 11th than on any average day, 14x higher than the average the day before, 6x the day before that….

steel alloy (the foundation of both WTC's) in this case MELTS at 2800 celsius, while jet fuel VAPORIZES at 1800 celsius, in other words:
the planes cannot possibly produce heat above 1800 celsius!!!
So how does the allow melt??

And tower 7 is just pathetic. It fell for no reason. BBC filmed it falling, on record, live, 20 minutes before any US media…

the list goes on and on..,…
if you look into it, you are convinced, period.

Ii don't undeerstand how people can turn their backs to this, it is disgusting.

yeah zionism stinks

Menachem Begin - Israeli Prime Minister 1977–1983

Our race is the Master Race. We are divine gods on this planet. We are as different from the inferior races as they are from insects. In fact, compared to our race, other races are beasts and animals, cattle at best. Other races are considered as human excrement. Our destiny is to rule over the inferior races. Our earthly kingdom will be ruled by our leader with a rod of iron. The masses will lick our feet and serve us as our slaves."

London, Feb 27 (ANI): One in five young British children have imaginary friends, says a new study.
When parents were quizzed about the "kind" of imaginary pal their child had, most pointed to them as other little boys or girls, some parents thought their child had fantasy pets or characters from fiction and many attributed their child's alter-ego to an entirely made up creature.

No I didn't but I bet Dave S still has them.(I know, cruel
In the context of the article, didn't we all?

I remember playing with toy soldiers imagining that I was the Captain, and that my "army" spoke to me! Or Scalectrix (?) , where you were the Lewis Hamilton of the time.

And why do girls play with dolls and prams!

Love your question, but I always get the feeling that many surveys are stating the bleeding obvious.
No but my younger brother did. His name was dinny (?) and my brother would insist he had a place made for him at the table…..I was evil lol I used to throw myself on the chair dinny was sitting on, nick dinny's food and tell my brother dinny was a girl….

He told me later on when we were adults that I had traumatised him, then admitted that HE was the one that cut all the hair on my Cindy's heads..such are the joys of sibling rivalry!!
Mine was a ninja. I would always imagine him jumping around, from rooftop to rooftop, always watching me to protect me from dangers. Never really interacted with him though since he kept his distance so I don't know if he could be considered a friend.

I watched too many ninja films and power rangers back then lol.
Yup, Harry Potter and Hermione Granger. I was like 6 that time, i was casting spells and wearing huge robes and stuff then i grew up knowing magic isn't real. But still, they're my idols.
All my friends were imaginary
I had to. I was an only child living 2 miles from the next nearest family with kids - and then my parents were too snobby to let me play with them! bummer!
actually my imaginary friends were actual people like my crushes it was way back, when i was 10 or 11
yes

mr nobody

i don't have any recollection of him but my parents do

none of my own children did
No, I never had any imaginary friends.
Not really, but I played in imaginary places.
Heh i had an imagenery friend from age of 12-16. I would keep the guy any day but I just stopped talking about him since.
Yes I did! How funny. We have such great imaginations as kids!
Yes I did!!!
And at times I still have them, they do exactly as I tell them and they are really beautiful people. :-))
mine was sonic the hedge hog
Yes i did.we were best friends too.
i never had any friends………even my made up one went away….

A lot has been said about how the media helped Obama get elected. I watched quite a bit and I tend to agree, they love him. But, he is not the 1st Democrat they loved. Bill Clinton was also generally cast in a positive image by the media. Negative things about them usually is the 4th or 5th story, but let any Republican do something, and that is breaking news.

Based on facts, what does the Democratic party do that is so great for the media? Was there a historic decision or some legislation that caused them to lean Democrat?
I am not sure of the precise percentages but I believe that members of the mass media are something like 80% liberal. This goes right up through editors and producers. That is their view of the world. No legislation no great decision just their natural tendencies.
Most Democrats and Liberals don't like America. They favor big government and a do what ever you feel like doing lifestyle. They are soft on crime, don't think Americans should own a gun, abortion for any reason whatsoever, talk to the terrorists, don't upset them, disregard immigration laws. They don't like traditional America. Period. They all learned the same thing in liberal classrooms by liberal professors who also don't like America. How the professors got to where they are is a puzzle to me. Those in the media went to the same liberal classrooms and were taught by the same liberal professors.

One more thing….the Democrats and their new king want a one party system in America. Do away with the GOP permanently.
For the same reason why some of the media tend to favor republicans. It depends of which tv channel or newspaper. Who owns it and all. Not all the media is liberal. Not all the media is conservative. Saying that all the media is liberal is totally stupid and idiotic.
Because most of the main stream media is liberal. They come from liberal schools, have liberal friends and think everyone else is liberal. And they think that if you are not liberal then you are a stupid redneck.
Bizarre behavior is sensational. Liberal behavior is bizarre. Sensation sells. News media sensationalize and embellish.
Most people in media are Democrats and liberals.

Edit:
The equivalent of Democrat outside the U.S.A..
John F. Kennedy and the civil rights movement. Equal rights for everyone. That's when I knew, who wanted what for whom.
They don't. It depends on the individual newspaper or TV channel.
Because they are the only Party that truly cares about this country, not their party.
