Birth control conspiracy

Then wouldn't the religious be for abortion and birth control? Then the non-religious wouldn't reproduce and the religious would be able out number the non-religious.

Yes, although im pretty sure this is a well known fact. Encourage breeding as a means of inflating your religion, because lets face it, conversions are waaay down. Religion-enforced pro-life agenda is not necessarily to ban it for everyone, but it is definately trying to prevent their own members from having abortions.
