What do you expect from SC, anywhere that sticks the label of 'only for intelligent discussion' is going to attract all the Dunning-Krugers far and wide. It's like that video where they're asked to blindly rank themselves by what they think their IQ is and the one that was just above average managed to bully herself into being ranked first (or close to) - the look on her face when it was revealed. Priceless.
The above comment is a bit tongue in cheek, you do get some good discussions there. The thing I hate the most on this forum though is that personal attacks aren't allowed. And people will thinly disguise it by replying to a post, and taking the jist of that post and implying things like: "People who hold <x> opinion are complete morons/mouthbreathers" etc. If they just said "You're a moron" it'd be a personal attack. But if you just say the people who believe those things are they can weasel their way out of it - even though it's clearly in response to an individual and targeted at them. It's just petty and sad, I have very little time for it. Just step into any thread in SC and it's full of people with similar opinions back slapping each other, and then snarky snide bad faith arguments, straw mans etc. for the others.
