Does the racism stuff really annoy people? Because to me that seems unnecessary. What I find really really annoys people is when they are already rather riled up, then you explain that the reason they are riled up (in an intelligent, well thought out manner), that it is because they are in every case inferior to you, or at the very least that it's down to their real life that their reaction is so over the top. Therefore a typical exchanged would be as follows:
General Souflete the Third teamkills JeffPenisOwner332 with a combat knife.
JeffPenisOwner332: OH WTF U FUCKEN NOOB Y TH FUK DID U DO THAT NOBOB?
General Souflete the Third: Oh sorry dear chap, didn't see you there, won't happen again.
General Souflete the Third teamkills JeffPenisOwner332 with a combat knife.
JeffPenisOwner332: OH FUK U IM GETTIN AN ADMIN UR FUCKEN HOUT OF HEER
General Souflete the Third: Why are you getting so angry? What have I ever done to you? I'm sorry if I accidentally hurt you, but it's not my fault that your inevitable shortcomings in real life are making you get overangry at me, just because you have obvious personal problems, it is not my fault and I am going to have to ask you to stop.
And so on and so on.
While this particular 'rage' was well done and well editted (must've taken a long while to cut out all those strips), a little more thought into the execution and you can end up with something both annoying to the person/people at hand, and intensely humorous to those who read about it later.
Just a thought.
