“I agree with you that every STATE should outlaw abortion and no STATE should redefine the parameters of marriage.”
The Federal government has no role in those issues, except that it can use the full faith and credit clause to allow states to refuse to recognize marriages that their own state law does not recognize.
This is an important point that EVERYONE misses - governments at different levels have different purposes but everyone talks about “The Government”.
At the Federal level I am rock ribbed fanatical libertarian. This government should only be allowed to do what is specifically allowed to them in the Constitution.
States have wide latitude to do what they want within their own constitutions.
Local governments should be able to do pretty much anything the citizens agree to do.
