Sorry about having to deal with that. I was raised in a similar environment and can very much empathize. At even an early age I started pointing out that what they were trying to teach me and what the book they told me to read were in complete opposition to one another. That didn't go over well, and it continues to not go over well.

Thing is, according to their own scripture, God doesn't need you to believe in him/them... just that you live righteously (a word that has different requirements depending whether you are ethnically Jewish or a gentile). Basically, be kind and generous to everyone, because God takes your treatment of others - especially the disadvantaged - very personally. Whether you believe in God (any flavor) or not, that's just good universal philosophy... and one that Christians don't just refuse to follow, but spit on.

So spitting on the futures of your own children and grandchildren... wow, according to their own "holy scripture" that's a big problem.
