Feel really crappy

I’m 18 ftm, closeted but have family who are openly trans and apart of the lgbtq+. I have an older brother who i’ve always felt close to due to some traumatic events in the past as well as our mother. He was a jerk in the past though it was never anything serious and he was a teen so it was the usual older brother picking on his younger sibling kind of thing. However a few months ago I was talking to him about the lgbtq+ and how he felt about it (as a way of gauging if it would be safe to come out to him as he is pretty good with keeping secrets from our parents). But his response..

TW// TRANSPHOBIA

He compared trans people to wearing a halloween mask. That no matter how much 'makeup' and 'detail is put into the costume', that it doesn’t change the fact that 'a werewolf mask doesn’t make someone a werewolf'. He refused to listen when I tried to explain to him and just cut the conversation short. Then I found out he is a Trump supporter and still supports him and said he would be voting. He never outright told us if he actually picked Trump but with him still liking Trump it’s most likely the case. I feel sick. Even outside of the case of transgender, he still picked the man taking away the rights of his mother, our sister and his other sisters which just- I genuinely care about him as he’s my older brother and he even offered to let me live with him and his family when i’m able to move out due to our own mother not letting me move out on my own without a partner (also closeted aroace so the partner case sucks)- but I can’t handle facing him if he did actually support such as man. I haven’t talked to him since everything and I don’t know how I feel about him as a person even. To know my older brother doesn’t even see me as a person who should have control over my own anatomy really stings.
