Welcome.
Glad you were never baptised.
any time I bring up my views it turns into a 5 hour phone argument
How about avoiding "your views" for awhile, and realise that mom and dad have their views, also. Just agree to disagree and talk about more pleasant things. They may feel like they are being put into a defensive mode. Look at all the investment they put into believing it...plus perhaps they feel guilty about your childhood and feel they must justify themselves to feel better.
Maybe just "drop crumbs" for awhile and hopefully your folks will eventually come to their own realization.
