Possibly I’m not framing MY argument correctly.
The Constitution and Bill of Rights do not “give” us rights, BTW. They enumerate pre-existing rights, which I’m sure you knew. :)
Theft, murder, rape, assault, fraud, and you name it are all illegal because we believe them to be wrong (immoral) and therefore passed laws to prohibit them.
It is bizarre to look back to the Founders as opposed to laws legislating morality (including sexual morality) when such laws were MUCH more prevalent then than now. Adultery, homosexuality, obscenity, blasphemy, etc., etc. were all illegal in their time and enthusiastically punished. I am not aware of any statements by any of the Founders, with possible exception of Tom Paine, that these laws should be eliminated.
“you have your own set of morals, and feel that these morals should be applied to everyone”
Nope. I have certain moral beliefs that I think should be applied to all. Murder, theft, rape, assault, fraud, abortion, slavery are morally wrong and should be prohibited. Other right/wrong (morality) opinions I apply to my own life, as best I imperfectly can, but don’t think are appropriate for the State to impose by force.
BTW, I think it is Adams who said something about the country requiring a moral people.
