I didn't watch it on TV, I watched it happen from two blocks away.
So, does it make my experience less traumatizing? This isn't a competition. I saw people jumping from those building same as you did. My grandmother had to console a cohort who had parents in the area when the attacks occurred. They saw both planes go in. She prayed with a bunch of students in the department she worked in because they feared the worst. She wouldn't tell me those things until I was older.
I think I could make a pretty strong argument that washing WTC dust out of my hair for days after is "more traumatizing" than watching it on TV.
But that's really not my point - my point is that you're using that trauma as an emotional justification for your views - and if I can avoid doing that, you can too.
Emotion is by definition not "objective".
