How to hate more
How I did it: I started watching infomercials, poltical debates, shows about celebrity gossip, and so on. After loading my mind with the inane blathering of a world gone retarded I found myself overwhelmed with hate!
Lessons & tips: You could start my trying to hold a civil conversation with someone to the far left of the political spectrum, that always gets my blood pumping!
You could also visit your neighborhood hippie, and listen to their view of the perfect world for 2.6 minutes exactly (it's 2.6 minutes into the conversation that they start blaming corporate America for all their personal shortcomings).
Resources: Best way to hate more is to realize that everyone sucks, and if you can't find anything about someone that sucks, you clearly aren't looking hard enough. Ah yes, and always assume the worst of others, because you will almost always be correct.
