How to support trans friend when my parent treats her horribly?
​
So basically I'm living with an adoptive parent and he's always nice to me but one of my besties is a trans-girl and she comes over a lot but during her stays my parent misgenders her on purpose and says rude things about trans people and says it's a mental illness.
Like how to get him to stop it cause it's really hurtful to my bestie and whenever I tell him transphobia isn't okay he just replies something like "my house my full authority and rules". How do I get this to stop and keep my bestie feeling comfy:(
how do I support her :( cuz my parent is being so rude to her and how do I get him to stop with the discriminatory 'jokes' and misgendering?
(I've tried telling him enough he doesn't listen)
I wanna support her but I don't know how to when he's making such a hostile environment for her:(
