I can't decide if these people are just ignorant or if they really mean what they posted. I hope it is the former (and they are just posting those comments because they can hide behind internet no-identity) because if it is the later they are just SICK!
From my own perspective I was caught in 30,000+ crowd in 1989 when Czech Republic got rid of communist government and let me tell you something: I am by no means weak person, but being part of crowd of that size is very strange feeling. Nothing went (too wrong) at that time but had those 30,000 people gone nuts then I (and I believe pretty much anyone here on subsim) would have crapped my pants.
People posting such stupid comments, do not have the faintest idea what they are talking about....
