Just because a large number of people choose to believe in something and may like to share it doesn't mean that everyone's being "indoctrinated". The sheer number of different religions, as well as the non-religious and anti-religious crowd, should be telling in that regard.

If we have the freedom to choose, what's wrong if you choose to believe in something that doesn't have basis in scientific fact? If it hasn't been proven, then it's wrong and no one's allowed to believe otherwise?

You wish to take away the freedom of choice. That's a much more damgerous stance IMO. Remove religion to promote choice? Isn't that the same as the "indoctrination" you so desperately wish to avoid?
