Interesting topic. To me, trolls - based on my experience - seem to be the ones who don't believe in what they post, and in fact do it provocatively to generate negative reactions and gather "audience". And by audience I don't mean necessarily honest audience, in fact they want quite the opposite, they want allies in fake opinions.
With that in mind, I come here with the true feeling of being a guest of Chris and his team, and try to behave as a guest invited in someone's home. Yet, I've had my fair share of disagreements here and I will not fake expressions of my thoughts for someone else's appeasement. I'd rather leave when that day comes.
