Anyways, anyone has a reason to dislike someone, but if you don't meet them in person you can't truly hate them, you more or less dislike them. Hate is a strong word and should take a lot to make you hate someone.
What I've seen from Kev thus far is nothing much, to make anyone hate him. But that is my own opinion and he could have done worse to those who are stating so. But really, hate is so strong and is contagious, everyone tends to target those who are disliked in a community, you want proof of this? Look in the history books. Hitler and the Jewish people are a good example. Don't be silly and put it in your signatures, threads, etc. If you hate someone, fine. But no need to publicize it, as not many people actually care that you do, except your little followers.
