While I refuse to enter into political or religious discussions, Kurzix, I have to take your parents side on this one. Of course I do not agree with their beliefs but I feel that since you're living in their home, you're obligated to do so following their rules. I don't think you should waste any more of your time or breath trying to convert them in their beliefs.
Be thankful you have somewhere to live and deal with it till you can get on your feet and back out on your own again.
Just my biased opinion as a parent.
