A lot of the western world has devolved into tribalism and identitarianism. People of similar views on anything are lumped in en-masse and presumed to hold all of the same values, opinions and support all actions of the collective whole.

It's a shame that a lot of core values are lost in favor of these viewpoints.

Yeah. It is really sad. We're getting hyper-polarized options and information everywhere we look, and it's affected people's ability to argue a specific point if they detect any misalignment of interests. I've been calling it "casually dismissing someone's opinion by lumping it in with an ideology", but looking for something more concise.
