Just look around and see who you know who has more kids,married people or single people. Also a tax on marriage would make sure that only people who really wanted to get married would be getting married and we would have fewer divorce cases taking up time and money in our court system.
Also Christians should not be allowed to raise kids,if they have kids the kids should be raised by the state that way they are not being brainwashed from birth. Also no one under 18 should be allowed to enter a church or read a bible. If they want to do it once they reach the age of 18 that is fine and nothing should be done to stop them but if they do it before then they are being brainwashed and told what to think,since they are not old enough to think for themselves.
