Hate is a very strong word, I imagine that your intention was to ask what annoyed/bothered/irritated us. I don't hate anything though. I don't even hate the concept of hate, because everything serves to balance and have opposites.
Annoyances: Nothing really, I don't let things bother me though I used to. It's just not worth it.
I hate (in no particular order) :
- Police (if any one or more of the above applies to them)
- The Bush Administration
