Okay, so here's my advice. Yes and No. If they won't even give you a chance then don't give them one. I recently came out to my parents (They're kinda religious) and it went well. My recommendation is to give them a chance if they're willing. It could clear misconceptions and make them feel less transphobic because you are and if they are your parents then they should care about you. If they are the stubborn type tho, then don't even.
