Child abuse ?

[pocaracas]

Natural selection will favor the kids whose parents or teachers provide them the best survival advantage.
Theres two factors prevailing here.
1. Parents love their kids more than teachers (the State)

Correct.

2. Religion has conferred a survival advantage for a long time.

Very debatable!
Even if it was once an advantage, it most likely no longer is.... unless you claim that people who go to church end up meeting people from different ways of life, and expand their web of connections, which may help to have a successful business.
That's why scientists have a lot of conferences; so they can expand their web and learn what other are doing in their field, or fields a bit on the side.
