I recently added some new people here: welcome! I'm gonna re-post some important info for y'all, as I am too anxious with strangers to have individual conflicts, generally.
Language is extremely important; it shapes our thoughts. If you value using any word that comes to mind without considering the consequences, we won't get along. There are a lot of commonly-used words which cause a lot of harm. The most common that I come across are probably st*pid, l*me, b*tch, cr*zy, and ins*ne. I've written a lot about this:
slurs are still very harmful when they are aimed at a situation/action/thing instead of a person / TW: slurs
we can't be friends if you use slurs because it damages me & breaks my trust in you / TW: slurs
slurs are both harmful and not expressive: say what you actually mean instead / TW: slurs
Other language issues that I object to and will unfriend people over include using rape 'jokes' or referring to stereotypes like they are fact (such as saying that girls like pink or that being assertive is masculine). Making light of rape is harmful. Affirming stereotypes is harmful. If I haven't addressed it directly with you I may assume you don't realize, but if it happens a lot and I don't feel able to discuss it with you, I may cut contact with you instead.
