Look, I think it a childish response for someone to feel the need to go after people for not being satisified with this teams performance, and to make it personal, ergo, the very definition of a personal attack. I know you feel the need to lecture me here and have the last work for giving said poster the same type of response to his personal attacks, and that's fine.
I obviously don't agree with your point of view, so if you feel the need to be superior too, go right ahead. I feel that if you are personally targeting people, posters responding in kind isn't crazy, especially when the feel the need to break another rule and make those attacks through PMs.
