Why of course the people don't want war. Why should some poor slob
on a farm want to risk his life in a war when the best he can get
out of it is to come back to his farm in one piece? ...Voice or no
voice, the people can always be brought to the bidding of the
leaders. That is easy. All you have to do is tell them they are being
attacked, and denounce the peace makers for lack of patriotism and
exposing the country to danger. It works the same in any country.
― Herman Goering
I love anonymity, I really do. I think the ability to have it is vital in any free society. Even so, I cannot deny that it has its downsides, and lowering social inhibitions is one of the more serious ones.
[edit: subject is mob violence leading to murder, etc]
It is one of many aspects that can contribute to violence in situations like these. I wouldn't say it is even a primary cause of the violence in this particular case, but I would say it plays a role.
