You don't have to leave, although I think most people overestimate how much it would hurt their social connections if they did. You just have to refuse to engage with toxic content when you see it, the same way you avoid debating with an obnoxious friend. (Newer social media platforms, unsurprisingly, are designed to make this easier; it's much easier to avoid dumb arguments on Instagram or Tiktok than Facebook or Twitter.)
It's you against a whole bunch of bright, motivated, and very smart people trying to keep you commenting, clicking, and getting involved. It's not that easy.
