My mother (and 99% of my family) is still religious. My nephew is another atheist born to religious parents. I don't think that idea of children automatically assuming the religion of their parents is necessarily true, though it happens quite often. But I'm betting that number drops as information is easily available on the internet. It was far easier to keep kids indoctrinated back when they actually had to go to the library to look stuff up.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
