As someone who doesn't believe any bullshit religion I will tell you what to do step by step.
For now you LIE!
Why? ---> Because you are still a minor in the custody of your parents.
LIE and make your parents believe you are perfect.
Then when your turn 18 and get a job and get your own place away from your family you can cut contact with by telling them you do not want to have a relationship because of differing opinions. Tell them you love them and that you are there for them in case of an emergency.
This is what I did and everything is good with me and my family. My mom still speaks to me but not my dad but that is okay because I am one who gets to decide who I want a relationship with.
