If you hate it because you're getting ganked (by me ) then reroll on a PvE realm!
PvE servers are fine. It's cool having that many of your fellow players around (unless you're asocial, then you should stick to single player games).
RP servers are fine. I'm sure it's great being able to find other players outside of Stormwind for once (as long as it is not Goldshire).
What's the hate?
