I don't know if this will help, but the stupidity level is probably no worse than it's ever been, it's just a lot more visible now.

Most human beings have never paid much attention to the world outside of the little bubble they live in. But now that we have such a good communication network they're able to get casual low-effort glimpses of the big world by glancing at a few memes or whatever, which they think makes them experts, and they broadcast their ignorance worldwide because they can. The ignorance was always there, just never this noticeable.
