AITAH for telling my older brother I don’t want him in my life, if he can’t stop calling me a sinner.

So I (f21) have and older brother who is (m30) and growing up I've always looked up to him until today when I found out he is homophobic. I'm bisexual and I'm out and proud. I found out cause my brother texted me saying I'm a sinner and all that stuff. He continues to call my mother a whore and that me and my other siblings were born out of wedlock and he wasn't.

He texted me today and told me I'm a sinner and how I need to repent to God. I called him a horrible older brother. Cause growing up he was. He was always going out getting drunk or high and getting arrested and now that he's married and has 4 kids he wants to chose God which I told him to believe what he wants and that I'm completely done with him. I've tried for years to be a great little sister but not once has he tried to be a great older brother. I told him that my sisters don't want anything to do with him and neither do I and he said I will regret not becoming stright and believing in God.

Now I believe in God but I also believe that God said to love everyone and that's what I'm doing. I told him I love him and wish the best for him but I can't and won't be in someone's life who calls me a sine everytime we talk and tells me to repent to God. And now he's going around and calling me an asshole.

He's calling me selfish for not wanting to be in his life nor his kids life's. I told him im protecting my mental health and peace from this Chaos and to never contact me again.

So Aith for telling my older brother I don't want him in my life anymore cause he continues to call me a sinner?

Edit: the reason I said I looked up to him was cause I did when I was a kid. He was my older brother. But now that im a grown adult and look back at my pasts I see how he was and still is an horrible older brother.

Edit 2: my dad just called me and apologized on behalf of my brother. I guess my brother told my dad thinking my dad would side with him when my dad encouraged me to come out in the first place with the rest of the family. And he told my brother thats not what a Christian is at all. And that he needs to reflect on himself before messaging him.
