I agree with jcg. He expresses the same thing I feel very succinctly.
Based on what I've seen, too many people like to make baseless statements and when someone challenges them to back them up with evidence will try to turn the argument into "You won't tolerate any one else's opinions."
In fact, you could say that's pretty much how the Customize admins got into their mess. When challenged to substantiate their assertions about WindowBlinds vs. Style XP they couldn't and so resorted to "you just aren't willing to tolerate dissenting opinions." All I was looking for was for them to explain why they felt the way they did with actual facts or experiences. Ashamed that they could not form a coherent argument, they launched into abuse and flame baiting.
That's just a recent example. Other poor debaters I've seen include people like Shoggot who will express very strong opinions but seem to lack the ability to put together a coherent argument. Remember his claim that the GUI Olympics were fixed because I made a complementary remark to Greenreaper? He posted on every website. It was a very flimsy argument that time has shown was false. But since he was already convinced that Stardock is "evil" (his words) it stood to reason that any actions we did must be "evil" as well. But when challenged to substantiate his opinons, he was unable to do so and quickly reverted to the tried and true "I'm allowed to have my opinon!" Even though he could not come up with a single legitimate reason to form his opinion.
I bring up these examples for a particular reason - The ability to provide rational arguments is important in a community. It could be argued that Shoggot's and Custo's loss of prestige and influence over the months is directly related to people seeing this inbability to back up strong assertions with evidence. That was, as humans, having lived in societies for so long, are naturally inclined to respect those who can articulate their opinions based on rational reasoning. And those that cannot inevitably lose respect.
This is one reason why I think that those who hold strong opinions should consider why they have those opinions before airing them in a public forum. For if someone challenges those opinions, one better be prepared to back them up with seemingly rational reasons (evidence).
Of course, in our particular community there is a higher than average intolerance for lengthy posts. In the discussion gruops I belong to, my posts are considered brief and pithy. Here they are long - because qualified arguments with evidence are difficult to do briefly.
