Hm, this'll be interesting, I've never put down this in words before...
I always make it sound like I hate everything. If you've ever been in the guildchat when I do Battlegrounds in WoW, you'd know this. I hate mainly because I cannot enjoy whatever it is I am doing at that time. Whiners, I hate. Griefers, don't even get me started. Emote-spammers? Burn in hell.
I don't hate because it's 'cool', or because everyone hates it. If someone tells me I should hate something because he/she does, I always ask them if I look predjudice to them. I try to always know what I'm supposed to hate and for what reasons. That said, some things I just don't care enough about to hate.
Hypocrisy is also one of my favorite phenomena. I constantly find myself being a hypocrit, and I find that fantastic.
But really, come to think of it, I can count the things I hate, the stuff that really makes my blood boil, on two hands. Other things I find to be just above a slight annoyance. I'm actually quite a calm guy, when it comes down to it, even though my guild mates probably think I'm a condensed ball of hate and rage by now.
