They argue in bad faith, they are rude and generally unpleasant.
I saw a few brave souls having civil discussions even if they weren’t profitable. You’re better men than I am.
Not that I want to be rude. But when the conversation leaves the realm of ideas and becomes tactics and maneuvering to win points, then I am done.
All they have is tactics, because their ideas don’t work. That’s why they indoctrinate kids, because they are the only ones who might be convinced by them.
