Considering that they are judging this community for being narrow-minded and despicable, they are not so different than us on that matter.
Seemingly they are blind to the point of how one could end up like a wizard (granted, one who never was bullied his whole life, was not a victim of shitty parenting and of shitty circumstances not see that some of us do end up lonely and mistreated, and even though we would like to fix things, scum like them will shun us away and call as losers, making this whole thing a giant windmill, with the results almost being the same no matter how hard you try - you will never be the part of the selective group of those who did not have much emotional (or other) hardship in youth).
They see themselves and us in their own way, and not only that, some openly want that people from this community would die. Such people made most of us what we are now - secluded from humanity, as they do not even give it the smallest thought to understand us, they only judge us by the standards they used to live in, being as small minded as they imagine the average wizard is.
We are the product of such people, who sees someone different as a bad thing, and openly hating us for hating them, when we are in fact only like this, because people like them treated us like shit for no reason.
And yes, I do see how some people would celebrate a person like Frank Vitkovic. After seeing how those people refuse to even give it the smallest thought that such actions of theirs was in fact what pushes people onto hating the world, and a man who stood up for it, because he could not tolerate mistreating of such social groups is, by my opinion, a valid person to be inspired by. At least by reading their forum, I see why a person would chose to shoot some of them.
No matter how deep misogyny and hatred of others run around, some of us have valid reasons not to trust or even hate people, what reason do they have to hate us? Didn't they had enough by making some random loner kids feel like shit their whole school life? And such people wonder, why some celebrate murderers.
