I’ve been saying this awhile, WAAAAAAYYYYY too many people are so rigidly locked into their political identity as a team, they see EVERYTHING that isn’t “with” them as “against them”. It is on both sides, though it seems the right has it worse than the left, in my personal observations.
I see just about every one, though, locking people into camps and labels, even if they aren’t as rigidly locked into team.
