At what point will you people stop bothering to try and to treat him like a rational person? Hasn't he demonstrated time and again that he is no such thing? Take a page from Hitchens when dealing with krellin:

Let him scream at deaf ears all he likes, it's probably the best choice. I did it for 3 months and it was great. Then I got bored and realized I could have more fun taunting him. Soon I'll get bored with that too and just not pay attention any more for a bit.
Look, all I'm saying is that all this shit isn't necessary. On the internet, the best advice is the advice your mothers all gave you. Just ignore it. Ignore him. I guarantee that if for a week straight nobody acknowledges a single "point" he tries to make, you'll see radical changes in his behavior.
As for my personal contribution to the problem? I don't know what to say. I have a decent working relationship towards almost everybody here, even those I frequently disagree with (Draugnar, Semck, gunfighter, etc.). Sure, I have moments when I get a little trololol in me, but it's usually for the common hilarity. Sometimes I overstep myself, but it's generally where you-know-who is involved. I just don't see any single thing as being too low of a blow in this regard. A person who exists only to taunt others deserves to be disregarded and treated with contempt. He deserves it - and worse.
krellin has a problem with everybody. Me? I just have a problem with krellin. If a few daughters got banged along the way, so be it. That being said, I definitely understand that kind of talk was not well received, so I'll try to moderate it in the future, lest I become closer in behavior to he who is most abhorrent.
