Advice/help needed!

I'm 15, I'm bisexual and I'm living in an extremely conservative, Christian and homophobic home. I've never said anything about my sexuality to my parents and I've never stood up to them about homophobic remarks because they will get suspicious and they will tell me I dont know enough about it/the bible says that it's wrong. They have an app on my phone that tracks me and can see my search history so I cant do research on LGBTQ history or research on what the bible says about LGBTQ people/relationships. (Btw, I'm not sure what I believe yet, still figuring it out but I know that if I ever want to take my parents on about their homophobic behaviour I'll have to use the bible or have an argument against the bibles claims)

If anyone could tell me about/teach me about LGBTQ history and what the bible says about LGBTQ relationships I would appreciate it so much !

Thanks a bunch
