I have never met a biblical scholar who denies that Mary was a young teen. In fact to the best of my knowledge there is not a single christian denomination (Catholic, Protestant, Anglican, Orthodox,... ) that believes anything to the contrary. So who are these Christians you know and do they actually _follow_ their claimed religion ?
I'm Catholic and this was never brought to my attention.
There were a lot of things which were left out which I sought out answers to later in life - like how Jesus spent the majority of his life in the Middle East, but is represented as about Anglo-Saxon as you can be. Or what was he doing between 12-30 when he suddenly reappeared and was baptized by John and starts his ministry?
Again, I was never informed of these things, and to be honest, I really didn't care. These "discrepancies didn't make me a better Catholic, nor did they make me want to renounce my religion had I known them.
By that standard, the guy on the bus who tells me about lasers from outer space that make his legs hurt when he talks about the government . . . he's a fair representative of "most scientists".
If you want to take random encounters with people on the street as representative of a philosophy, you have to at least go to a place where that philosophy is practiced. To talk to the 'average scientist', you'd better at least be looking for him on a university campus -- better at a conference somewhere. To talk to the 'average Christian', you had better at least be looking in a church.
It's not just a sampling issue; those groups also police their membership. What you want to take an average over is not people who declare themselves 'hackers', but people who the community of hackers agrees are 'hackers'. Best way to do that is go to where they meet.
