My parents think I am joking about being gay.

I came out to my parents one night where I sat down with them. I just decided to blatantly say it and tell them to ask me anything regarding my sexuality. It was a long conversation that was mainly pinpointing the idea that they have never seen me with a woman and thought that was the reason why. Eventually, at the end of the night I thought everything turned out well as I gave them so many examples and analogies. I was relieved. It was the only burden that seemed to be lifted as I was only out to my close group of friends, cousins, and my kid brother. They've all understood it well but it was difficult for my parents as I've always known they had some sort of aversion towards homosexuality. The next day I come downstairs and my dad would subtly hint that I needed a woman to "make" me straight or that overthinking has led me to become sexually attracted to men. This made me incredibly frustrated as it seems they didn't grasp anything that I've told them. My mom comes home and we have this huge argument. I told them that I was not joking at all, that this was not my decision to begin with. My mom tells me to just live my life and she does not care whether I am with a woman or man, but my father on the other hand, thinks I need to have some conversion therapy. It's like everything I say will just end up being sucked away into a void. This really saddens me as they think I am purposefully trying to hurt them. I feel like I am trying way too hard to try and prove to them that this is not a joke. I am just going to live my life whether they accept me or not. What do you guys think I should do? Should I just brush it off until I'm able to provide for myself?Tdlr; came out to parents, accepted at first but then thought I was joking the entire time. Father suggests conversion therapy. Parents refuse to believe that their son is gay.
