Possibly the main issue of interest in the global warming thread is the split in the sceptical community over this topic. This can range from the patronizing and arrogant tone of someone such as Irish, who dismisses arguments with hand waves (because although he cannot refute the argument he thinks he already knows the answer), to those who mock, insult, yell, or try to shut down debate by other means. And then there is the silent majority - most of us. Star examples in the community include Randy and Penn and Teller. And then there is the very vocal politically motivated minority, who try to shut down discussion on the issue, except for their peculiar perspective. Of course, there are actual "deniers" and crackpots out there, so the effort from this group is to always try to smear everyone with the same brush.
Unfortunately, if I crack a joke, i.e., that someone failed in their application to achieve a sociology degree, and that necessities a moderator warning that I have gravely insulted someone, well that is both rather pathetic and sad. Especially if it's in a forum that has had until now, virtually no moderation in it. For me personally, very strict moderation should always have been the norm here (although this would involve great deal more effort from moderators so I can appreciate why that might not be a first option). Because, I assure everyone, when a small group is name calling and yelling, and distorting facts with impunity, heavy moderation is preferable to no moderation. For me personally, I don't give a shit and will always stick to the evidence wherever it points, because I don't have much to loose in the community (unlike Randy or to a lesser degree P&T). I don't need to be politically correct, and I don't need to present a particular perspective consistent with a particular political outlook. Obviously though, if I am receiving moderator warnings for the most trivial turn of phrases, that is effectively a ban on my ability to communicate anything at all. Anyway, good luck all for those who now post in the echo chamber.
