I understand maybe you were trying to 'help', but Mish, just because YOU don't agree with her style of expressing herself, it doesn't make it wrong. It's almost as if you are insinuating that if she posted more like YOU, she would be doing it right, or 'better'.
Vash does deliver some very sound advice, and the manner she does it has never once offended me, which is why I 'sided' with her. I don't understand why Vash in particular irritates you so much, but maybe you should just relax and let people say what they gotta say. Debating a point is fine, but picking at someone's overall character is another thing.
