No offense intended Moiraine, but yes, it is anecdotal. You're basing your opinion off of your perspective and experience. You're not providing facts or research to support your perspective. I do think subjectivity plays a massive role here. I have seen people gloss over objectively trollish behavior but report someone else's "trolling" in the same thread or string of posts. Can I quantify that for you? No. But I've seen it happen on numerous occasions.
That's why we're more inclined to allow people to share opinions. Some of you think they're just trolls. I don't personally believe that's always the case, and I think much of the behavior they're accused of displaying is either a) returned to them in kind or b) sometimes displayed by those accusing them of being trolls. And in those cases, I'm not interested in playing a parent over two children who are teasing one another relentlessly. I'd rather tell them both to knock it off unless there's an objectively clear fault. There sometimes is a clear fault and we handle those situations accordingly.
But, as I mentioned, there's no rule here against being a nut job or radical. I think a lot of people here could do a much better job of listening to one another as opposed to reacting, and there tends to be a lot more of the latter.
