Why you will go to hell if you are gay

Today my parents were going to church, and asked me if I wanted to go. Ask, of course being used loosely.
The church is shit. I don't believe in such an establishment. The things they say are utterly ridiculous, and prayer? Repeating the same chants over and over and over again. Can you imagine how that would feel if you were God. Everytime you get a call the person says the exact same shit as the predecessor for all of eternity. I've prayed enough, I prayed for so much and none of my prayers ever got answered. I prayed that God would always keep me close to my friends but now 4 years later and I haven't seen a single one since then. I prayed when I was 4 that my cousins and brother would stop hating me so much that they would stop trying to make my life hell, that they would leave me the fuck alone before it did any long term damage. It wasn't until I started school that we became cool. But enough self pity and of my sob story, I'm sure people have gone through worse and they've prayed too. I'm tired of it, prayer that is.
I decided that God is merely an architect and nothing more, the Church is a silly organization of pedophiles crafted by men and it has no direct correlation with God. And I decided I would go one last time to confess my 'sin'. So I told the priest my plight. I told him how I've been through some terrible shit, which I have chosen to omit in this passage. I got the same response as every other fucking time. It's like he didn't even care. And my penance? An our father. Renouncing the entire church gets me an our father, last time I had to say an entire rosary of prayers for jerking my meat.

So fed up with this shit, I talked to my parents. My mother was easy to convince, that I was possessed by a fucking devil.
My father put me on a guilt trip and shot down my beliefs, and then told me were going to church. Now I haven't had the best relations with either of them, infact talking to them is taxing. My mother is an idiot, and my father thinks everything he says is right. Among the life lessons he taught me was, "everyone will betray you, you can't trust anyone even yourself."

Tl;dr version how the fuck do I get my parents to accept or at least acknowledge my belief (Deism)? And no I don't want to have an angsty conversation with them, I only care enough about this to make a GD thread.
