Although tags might be a good idea, separation of subjects aren’t in my opinion. I think a big part of the community and the interesting things we’re able to find here are a result of the interleaving of the subjects you mention.

I do however really get your problem and I’ve had problems with it too. However I realised after awhile that it would be undoable for me shape everything into this mould I can deal with. So I decided to change the mould itself so to speak, nowadays I for instance try to read over certain stuff and actively ignore it and I only check the news as much as is needed to stay generally informed.

I don’t think you should necessarily do the same but it might save you some time and energy. Changing myself seems easier to me than changing the world around me. Stoicism has some good pointers about this although something as broad as stoicism isn’t necessarily needed. Something simpler would probably suffice.

(Mind you that I for instance didn’t have a problem with ideas which clash with my own, even more so I more often think those are the most interesting, what I do have a problem with is the lack of nuance which seems to be so prevalent these days and the tendency of people to make a personal and passionate affair of everything.)
