How to confront a weebaboo friend

So I’m not sure if this is pretty common in the anime community, but do you ever have that one very good friend of yours that likes anime but to an extent where they start to randomly talk in little bits of broken Japanese, try to sound “kawaii”, discriminating other non-Japanese work as ugly, literally saying they want to become a guy and then become gay because of yaoi, and tries to emphasize how ‘alt’ they are? Because that’s the situation I’m in. And honestly I don’t have a lot of friends and we’re pretty close, but I just don’t know how to break it to them that it’s kind of uncomfortable talking to them whenever they bring up anime/manga. I also have another friend who is more like a ‘try hard’ weeb. They like to act “quirky” and it shows. They’ll also try pretending they’ve watched an anime and then say things like “why are you trying to get in the way of what I love” acting like they’re the victim... my biggest problem with them is that they like to gate-keep. Idk if I’m just overreacting, but I really don’t know how I’m supposed to keep going acting like nothings wrong.
