Except for the military, and immigration, the constitution does not say the fed has anything to do those other items.
Every state has its own laws regarding divorce, adoption, etc, and that is as it should be-some states are community property states, some are not, etc.
The constitution says the fed can maintain a military, and makes the rules for immigration from other countries. I don’t see anything about private issue regulation there, none at all.
States make their divorce and adoption laws, and the people of that state decide. Where it goes is up to them, and should be-we are not all the same.
I do not believe personal issues are the business of the government, period-I said just that, several times-it is a slippery slope at best. I’m not going to go snipe hunting.
Well, they aren’t just personal issues if the feds and state governments are right to make law regarding them, as you agree they constitutionally do.
Frankly your posts seem confusing and confused.
