The part where the emotional needs come first, and the ideological belief comes later as a way of expressing and justifying them, that feels credible. I just don't think that everyone starts from the position of hatred (or, in the naive view, not everyone ends with hatred). There are other emotions, too.
But maybe the people motivated by hatred make a large part of the most mindkilled crowd. Because other emotions can be expressed legitimately also outside of the politics.
