My father is horrible and I don't know what to do

Little bit of backstory: I am a working adult, married, living on our own, and haven't spoken to my father in three years. My parents went through a nasty divorce about two years ago because my father is an abusive a** We all cut ties with him as soon as possible and he moved to frickin Wyoming or somewhere to join a cult, I don't know.

Anyway, I made it very clear to him that I do not want contact with him and have since ignored any attempts at communication he sends me (this is mostly to protect myself as I have 15 years of emotional and physical abuse to overcome and I don't need him gaslighting me). So all has been relatively quiet until my sister came out a few months ago. I was vocally supportive of her and helped her deal with extended family that has more conservative views. Shortly after that, I started receiving religious pamphlets in the mail that have been postmarked from Wyoming. I'm fairly certain they are from my father given that a) he hates the LGBT+ community; heck, he's told me he wishes gay people could be arrested like in his day and he forced me to go to counseling and get my hormones checked when I came out asexual. b) he's very religious and homeschooled me k-12 to try and keep me away from "satan's schools" and believes anyone who supports the "gay agenda" is going to hell. c) ironically, I was his favorite child and I think this is an attempt to either save my soul or get me to contact him again.

I don't know what to do. I'm tired of getting these things in the mail on a weekly basis, but I don't want to tell him to stop as that would be breaking my no contact with him and opening up an opportunity for him to talk to me. I just, I'm done and really wish he would stay on his half of the country and leave me to mine.



TL;DR: my father is an a**hat who won't stop sending my religious pamphlets in the mail after my sister came out and I supported her. Don't know what to do.
