Hi @Coby, first off of just like to say I’m really sorry about your family. Religion when handled wrong can be…. yeah. Second of all, I am going to offer you a huge virtual hug.
I’m not a professional by any means, but here’s some advice. Basically, just take it really, really slow. One tiny little rebellion at a time. If you keep this up for long enough, they could slowly start to be more open minded (slowly), and although it might try your patience, a negative response will hurt a hell of a lot less this way. If they get mad at you for something you say related to this, hit them with a strong argument. Make them question their beliefs, but like I said before, in very, very tiny amounts. Slowly. Whittle away at their resolve. Whenever you end up coming out to them, hope for the best, but be prepared for the worst. If the worst happens, which it hopefully won’t, you’ll be as ready as you can, and in the best state to fight back. Your argument needs to be strong. Extremely logical. Anything lgbt+-phobic that they might say, rebut it so that they’ll get to a point where they just can’t argue any more.
When things get hard, we’re here for you we promise. We all believe in you. Don’t give up, you can win this fight. You are your parents’ child and you do not deserve to be shunned.
