I think this is the problem with discussion forums. When you argue for logics/arguments sake you make simply retarded statements that have nothing to do with the real world (read every immortal pigs post). Sure in some idea world where only theory is applied, some of the arguments pig has used might work or be realistic. But in the real world, everything he has said thus far has been utterly wrong. I don't know if pig is playing the devils advocate or if he's just dumb, I can't tell but all the arguments he has made have either been based on semantics or some abstract philosophical ideas (and usually filled with logical fallacies)
To me this kind of discussion is banal, sure it gives more to talk about, but the quality of the discussion is simply worse. Especially when the other person is grounded in reality and the other isnt.

EDIT: Some homophobes paranoid rants are not exactly top notch discussion material to begin with.
