I will admit that there are some people who you just can't talk (argue) with. I have been lucky not to have dealt with a lot of transphobic folks. The closest thing to it for me is being the youngest child. I have, and probably always will be, viewed with less respect than my older siblings simply because of birth order. I have dealt with this by not depending on them for my self respect. I haven't disowned anyone, but I also don't seek to talk about areas of trouble with them either. I set my ground rules with them. "I want to keep you in my life, but I will not talk about A,B, or C. If you persist on making me uncomfortable, I will be forced to make changes to our relationship." What I am saying is spell out what you don't want to talk about. If they violate your rules, they don't deserve the privilege of talking to you. You have to KNOW that you don't deserve hostile friends or families' disrespect. Of course, if they are respectful, you get a chance to educate them.
Does this sound realistic?
