In a few short years you will be an adult, and your are free to abandon, spit on even your parents irrational religious beliefs.
For now just suck it up, and when the time comes let fly and tell them "I am dead to you and glad of it you religious freak."
It will totally be worth it.
(HINT this forum has no sarcasm icon)
Or just realize your parents religious beliefs, like 99.999% of everyone else who isn't you doesn't share your belief.
I was at my partners for xM-s dinner and I 'conveniently' had to run to the toilet right during the praying part. (AKA if you don't get I was deliberately dodging having to pray to their 'god'.)
