Is AUTHOR wrong in the post ? POST : My father tells me he loves me and I don't doubt that he would protect me from physical harm.

HOWEVER,
My father is  against anything "out of the norm". Which has caused me to hide many things about myself from my parents (sexuality,gender)  I used to question if I was trans, genderfluid, ect because ive never been overly feminine and honestly it pains me to think of myself as a girly individual. Ive also changed my name because the thought of hearing my old name made me uncomfortable and brought a lot of self-hatred towards myself.

 I had started going by my new name with some close friends for 3 years before I even mentioned it to my parents...thought I would start there to see how they would react and see how open I can actually be with them. I understand that after 18 years of calling someone one name and then asking them to to change that, is quite the request. Being my new name helped me feel more confident and most friends were accepting of it. My mom tries, she really does. But my father will go out of his way when people ask ME which I prefer, to interupt before I get the chance to answer and say "it's (old name)" 

Other things he does I'm not sure if it's to get under my skin or if it's just because he's an asshole. 
-i was dropping off a friend at her house and he goes "I've never seen such a fat Asian" first off he didn't even take the time to look at her in a none judgemental way to see that she's infact white af, and she's really not that overweight.
- I got a text at dinner and he asked out of the blue if it was from one of my trans ftm co-workers. "Oh is that oliver? How is SHE. doing?... Me and my mom both look at him like wtf "what ITs name is Olivia right?" Hes not doing this on accident as I have explained everything to him before... This one in particular really bothered me because how would he act if I opened up to him about my gender stuff?
-when we go on trips he calls the more heavy set people in the pool "whales" 

All this random shit he does gets under my skin and I don't have time for it.  Would I be an asshole if I went no contact just because I don't want to deal with this anymore?
