I see this exact thing right now to me and some (former?) friends, we’re all in our early to mid-40s. And, yes, it does involve politics, and more generally how one sees the world, but I personally find it quite baffling nonetheless. It’s like people really do feel the need to continue living in their intellectual bubble-balls, no dialectics involved, no contradiction, and hence no real (intellectual and not only) move forward.

I can’t and don’t see an easy solution for it, to be honest.
