It's the troll-rating system, with which I disagree. And you are correct - there are many people who post wildly opposing viewpoints who are then squelched. Bad on them. But I also think the tone is set by the poster and reinforced by a willingness to stand and defend and not resort to name-calling. I've been as honest as I can be, disagreement notwithstanding. And I appreciate the courtesy - with a few exceptions, it's been nothing but that this entire evening.
