Your argument seems to be that if you can’t prove a negative it establishes the positive. This is illogical since it is logically impossible to prove a negative. In any case it is not true that there is no evidence of this practice. In his ‘Histories’ Herodotus claims that an early king of ancient pre-Classical Libya uniquely practiced the right of the first night, and no one else in history had even done it.
I’m not going to claim it either way. At this point, I’m going to drop it completely. I think marriage, as MARRIAGE, should be a function of family and the Church. Contracts and their enforcement are where government, state and LOCAL, are properly involved.
You like a much larger role for big government. I want the least possible. Protect and respect the equal rights of all; don’t even THINK about special “rights” for “special” people- don’t even DREAM about them; tell would-be busybodies that some folks are gonna sin and that’s just that. If no Rights violations are involved, no outside party injured, just deal with it. You can preach the Gospel to those sinners who might listen, but you may NOT USE THE FORCE OF GOVERNMENT to get them to do things YOUR way. If minors and the incompetent are not being misused; if no one is initiating force, YOU may not get GOVERNMENT to initiate force to stop someone’s behavior simply because it offends you or you consider it “sinful.”
