> My favorite Tweet ever was someone who described this process that dudes do where they show up, take over a hobby, and drive all the fun out (and thus women) as "MENTRIFICATION". It is my new favorite word. You seemed to have missed that part.
I don't think it is inherently sexist to suggest that men or woman may exhibit certain behaviors more than the other. I am not sure when we crossed the line that making any such suggestion is inherently sexist.
Rather than saying the word "mentrification" is sexist, which is a complex question (like nobody is being hurt because someone on twitter comes up with a funny phrase), I'd rather say, if someone used mentrification in earnest, they're probably a shitty person and I don't want to hang out with them.
