Honestly? That's just shoddy parenting. I also despise the catholic zealots, but that's another tangent. I'm in a total grey area of "is God real/fake", and question my parents' beliefs all the damn time and they have never once said "they have failed as a parent." I also have an abundance of religious friends alongside agnostic and atheist friends as well. The most that we do is debate on the aspects of science and religion, and never had anything close to a falling out. In fact, it's made us better friends because we aren't afraid to question, debate, discuss, etc... But, like all things, bad apples can ruin the whole bunch. I'm a firm believer of judging a person by their own merits. If you're an asshole Christian, then I -blam!-ing hate your guts. If you're an asshole atheist, I -blam!-ing hate your guts. Conceited as it may sound, I want people to judge others the way I do.
