Why are men going on women killing rampages always MRAs when that is one of the most effective ways to bolster feminism?
Why do you think it is in favor of feminism?
When men go on killing rampages it's actually in favor of the feminists, because we are fighting against those "evil toxic masculine norms" so it's actually a promotion of feminism and we should continue doing it
There really is no justification for killing anyone, no matter who you think it supports. I'm sure feminists would not approve of any men inflicting violence on other men.
