A very reasonable point of view
I think most religious restrictions have basis in some practical application.
Jews and Muslims are probably restricted from eating pork because, at some point, it was a health risk.
Christian restrictions on sex probably have to do with STD's (if you only have sex with your virgin spouse, you won't get any STD's), and/or the fact that it's not usually a good thing for the child to raise a child without two parents.
Of course, birth control is bad because the church wants more Christians
Lots of children are good for the religion and expanding a society, but TOO many can be a bad thing. Look at the conditions of the Christian parts of the world compared to the Hindu and Muslim parts of the world (two religions that breed like fucking rabbits).
I may not agree with the means, but the ends cannot be disputed. Most of the Muslim and Hindu world is a fucking shithole, while the Christian-based western world is on the cutting edge of progress and high quality of life.
