"Swift completion" is relative to the game, not the community

I don’t like people /snip

Do you even go outside? Communicate with the general population at all? Maybe you cowering behind npc driven and single player content has only further developed your phobia. You are being irrational. If the duty finder, and the people in it are that bad, maybe its not them. But in the case that it is, you can always tab your chat over to battle info or customize one that leaves out say and party chat if you are really so sensitive.
Or you can pull those socks up and pull yourself together. Most of this community gets along just fine being thrown in with random. If you are that afraid, and that withdrawn, its less a community issue and more a personal one
