Just thought this was relevant to the conversation:
I prefer to have an actual debate if my opponent is capable, but often they are not and resort to all kinds of illogical semantic games and personal attacks. At this point, yes I will absolutely troll them for my own amusement as well as to demonstrate their motivation of arguing from a position of lack of emotional control rather than logic. If you come at me with anything other than solid logic, one way or another I get my pound of flesh.
Of course, he is the arbiter of what constitutes "illogical semantic games and personal attacks," so he gets to decide when his trolling is justified and when it isn't.
