This is a small board, and it’s entirely possible for coincidences to happen.
For example, it’s possible that, due to pure chance, the only people here who advocate for certain views are complete assholes. Is that the fault of the views, that the only Dopers who take up their banner are assholes? Possibly, if there’s no way to defend that view without being an asshole, but you have to examine the view closely to come to that conclusion. The chance makeup of the confluence of people here doesn’t prove the point.
There’s a way around this, or at least as good of a way as I’ve ever heard: Steelmanning, the opposite of strawmanning. When you strawman a position, you make it weaker than it should be, and attack that weakened version. When you steelman a position, you make it as strong as you can, and then attack that strengthened version.
This doesn’t necessarily mean the steelman wins. Some positions are losers, and remain losers even when steelmanned to the furthest honest extent. However, if you think the steelmanned version is laughably weak, you probably owe it to yourself to do a little more research on what the supporters of that position say in its defense.
We can’t really practice steelmanning on the SDMB because Devil’s Advocacy in GD is trolling, correct? Like, I couldn’t take a radical anti-gun-control position, defend it to the best of my ability, and remain a member in good standing, now that you’ve all read what I’ve posted in the Pit the last few days, right? So that could be the opening for the purely anonymous GD, or some other forum: Encourage posters to take steelmanned positions in debate, in a forum with no publicly-apparent usernames, so nobody’s “trolling” by our definition, but higher-than-normal debate standards, so people actually do steelman or, at least, do their damndest to put forth the best versions of positions they actually do hold.
