1. Some of this is your fault. Apparently they had been trying to converse with you in chat but you were so focused on pew-pew-lewt that you just charged ahead. 1a. In PUGs it's generally a good idea to wait and see if they are actually active before charging in, especially if one of them is in healer role (ie: killing your non-role healing bonus). It's annoying when people queue in then just stand around but it happens.1b. Having chat up at the beginning of a PUG is also a good way to see if anyone is wanting to go after a Feat (remember your quote about being a team? that's hard to do if members aren't communicating).2. Welcome to the wonderful world of "trash talk" (yes, name-calling like that is a direct descendant of such, it all boils down to ego-stroking through lack of respect for others), it's not just prevalent here and other games but it's a part of most competitive venues both online and IRL. Your only real options here are learn to ignore it or spend much of your ingame time reporting people. 3. Venting, over-dramatic or otherwise, is sometimes needed. The most important thing to take remember though is words have only the power over us that we give them. Sure, they shouldn't have been such Richard Craniums but you let them win by allowing their words to throw you into such a fit.
