Jesus Christ, the sarcasm is thick. You even used the word "wrongthink".
It's not a conspiracy or anything like you're describing, it's that moderate politics is often just... wrong. Believe it or not, there's sometimes a right answer, and a wrong answer. And if you go "in the middle" you end up being wrong.
I mean, take a small gander a history. There's usually a right answer... and a wrong one. Typically, in the moment, the people don't know that. So some construct middle-ground that they believe seems reasonable. Then, we look back on it, and say "what the fuck were you thinking". And that's how we end up with bullshit like the 3/5ths compromise. Seriously, what the fuck was that?
Point being, simply being moderate or depolarized doesn't save you. Consider that, in some countries right now, moderate positions are pro-genocide. Because that's how far gone the politics in said country are.
