Please don't compare people doing something fun to terrorists.
How's that for comparison?
If you want to sit and be misrable in peace do it, just don't try to force everyone around you to be misrable and afraid of anything but bovine normalcy.
I won't bother responding in the thread further, since you're determined to overreact to people having fun. In fact, I'll go watch more of the videos and SMILE in the most guerilla style possible! And I'll think about my two friends that died in 9/11 and how much THEY would have smiled at them too.
