Please, as if Facebook would be taken down when a few pubescent mongoloids "glorified violence".
Glorification is a matter of free speech, because it is an expression of opinion. That you find it distasteful is fine, using that as a weapon is not.
Either way, Facebook won't be held accountable because it's funded by large investment funds, and HN won't complain because they're in bed together.
The "too big" argument is not a moral argument, that just says "we have money invested in it". If that's acceptable to you you have no morality.
