I stumbled across this forum comment. Since I can't link to specific posts, I'll just quote it here verbatum.
Point one is terribly wrong, I think. I know people who PvP and they're very nice. kaelspriest must've had too many bad experiences.
Anyway, the other points are closer to the correct side of the circle than outside it...

I don't like PvP.
1) I don't like the culture of hostility. My experience of people who like to PvP, overall, is that they are *jerks.* Not all of them. Perhaps not even a majority are actively jerkish, although most seem to tolerate it. But it's enough to completely ruin my experience in battlegrounds and on PvP servers. And I'm not talking about the opposing faction - I'm talking about *my own side.* The sheer volume of viciously insulting chat in PvP areas is enough to make me never want to do it.
2) I'm gay. I don't like being called a f*g/got. Or a p*ssy. I don't like being called gay as if that's a bad thing. I don't like being called a girl as if that's a bad thing. I'm also extremely upset by the n-word and other racist language just on principle. And the PvP community is full of all of that - not just in the jerkish behaviour I covered in (1) but also just thrown around casually. I'm not all that thin-skinned about it - I actually enjoy interacting in trade chat, because even though there are some people who troll with derogatory language, there are also a lot of decent, intelligent people who will call it out. But that balance isn't present in PvP environments.
3) I'm primarily a healer. I like healing. I do not like being CCd. I do not like CCing. I do not like being interrupted. I do not like spending time trying to avoid being interrupted. It is impossible to simply go into an organized PvP environment and do what I like to do - I spend ~80% of my time doing things I don't like to do.
4) I don't always want to fight. I don't even particularly want to fight NPCs most of the time - I'm a champion at avoiding combat (probably because I'm a healer). When I want to do something, I want to do it, not fight someone/something else for the opportunity to do it. People who want to encourage open world PvP seem to operate under the assumption that everyone should want to fight, all the time, and should be willing to endure all manner of inconvenience (see: removal of HGWT, no flying until 90) in order to arrange it so that everyone is in a position to be forcibly engaged in PvP combat at any time.
5) I like being able to talk to the people I'm playing with. All of them.
6) I think PvP is bad for the game. It limits possibilities for everything from class balance (shamans can't be buffed because it would make them more OP in PvP!) to travel technologies (we can't have HGWT or flying because it's bad for world PvP!!)
7) I don't think MMOs are the right platform for PvP competition. MMO PvP is inherently, permanently unfair, and the more depth there is to a game's PvE gameplay, the less balanced it can be for PvP. Strategy games (Starcraft II rocks!) and shooters are much better PvP platforms, and I wish people who wanted to PvP seriously would go play games that are actually suited for it.
I especially agree with number six. PvP ruins things for the rest of us because it demands that all classes be balanced in ways that they wouldn't otherwise need to be. Because of PvP, everything needs to be reigned in.
