Would you be angry if your child chose/s a different belief?
Just curious.
I plan to let my children decide for themselves, as long as they are not hurting themselves, someone else, or forcing their beliefs onto someone else.
Why? Because my future-children may "be a part of me", but they are (in the future) different people than I am, thus they have their own minds and can decide who/what they want to be.
It wouldn't bother me ...
I would teach my child from a young age about the ubiquitous concept of "God" ... but as they got older, I will teach them about different religions and beliefs, and let them make the choice that fits them best.
