I guess it reads as a little gross or awkward on the surface but those are all signs of people who are feeling lonely or powerless.
When you’re really turned off by a post (or posts), try flipping it the other way around and see if you can feel your honest concern. Don’t patronize the person and make a big deal of the post, but act constructively: reach out and say hi and share the things that you like about them.
And if you can’t feel moved to do that, that’s fine. You’re not obliged to do anything. But it just might make you leave less grossed out and it might do your friend some good.
