My girlfriend wants our kids introduced to "all major world religions"

[Tiberius]

My view: Introduce them to as many as possible, but always with a skeptical eye, as you should introduce them to anything. Teach them critical thinking from an early age, and they won't be taken advantage of later on in life by people with promises of eternity. New religions form every day, so you're never going to stop them getting exposed, even if you want to. The best thing to do is to prepare them, and after all, it's not the end of the world if they become religious, as long as they make their choice after thinking about it critically.
