Oh, I've definitely done my share of debating, but at a certain point there's really just not much more you can get from it. If I'm going to debate, I'd rather it be something where one or more sides actually discusses and learns something about the topic, even if nobody actually changes their mind. This, for the most part, has completely devolved into a fairly base set of interactions.
Certainly there's something to get out of "I present things this way, and this class of people responds that way"; really just studying psychosocial behavior in response to various stimuli, but I just don't see there being much to learn from this particular conversation, with these particular people.
Now, if the level of discourse were actually raised from its current state... maybe you could get something from this... but at its current state, I'd just walk away.
As an observer though, I'll still check back and see what happens. I'm not particularly invested beyond curiosity at this point.
