Since Liberals have no theory to back up their worldview, they fight with labels instead. "I'm a progressive/Democrat/European/neurodivergent" etc. Obviously, identity is very important, but the way Liberals use labels and identity is like bonus points in a video game. They use the "winning words" to give themselves +12 discussion points towards winning the argument.
So naturally, all they have to do is say, "Uhm, I'm from X country"
and pretend it's core to the discussion.
