I think everyone with a niche skill experiences that to some extent. Almost all posts about mathematics on lemmy attract people acting like they understand what’s going on while making wrong claims lol, I only rarely see comments that are fully correct.
I don’t think I saw any math related post tbh, other than witty 3! = 6 one
I guess me being a mathematician makes me notice them more. I’ve seen many in several communities, but me being biased makes me wish there were more.
I just began math PhD program, maybe it becomes different after finishing it. Maybe we are in different communities? Mine is mostly this one, linux and programming.
