Great topic with some very sensible replies!
I am just speaking here as a member of the IPK Forum because I haven't visited or been active in any other Forum of IF.
Although it's true the MODs are dealing with quite an active Forum, and trying their best to maintain what they call peace and harmony, it's also true that there are times, and nowadays its happening quite often, when topics are closed just because an opinion of a minority was being stated there, just because that post wasn't worshipping His Highness, Barun Sobti, just because that member was calling a spade a spade.
We know these get reported and the MODs have to see towards it but many a times I have observed that MODs do just that- "see" the report PM and CLOSE the topic. What does that hint about their maturity level? A bunch of teenagers, when a post falls short of their drooling range or its tongue-in-cheek matter flies over their heads, report it and the topic is closed? A couple of stupid, meaningless comments in the midst of a healthy debate and the whole topic is closed? A post being trespassed by 13 year olds who, by the way, aren't even supposed to be sneaking around here, is apparently the Topic Maker's fault and- wait for it- the topic is closed?
Forget Freedom Of Expression. This is plain immaturity, of which the MODs must not be a part...but apparently, they are.
