“It is call equal treatment under the law.”
Equal treatment under the law is not required of the federal government.
The federal government can draft males and send them to the jungles of Asia to fight and die and give free goodies to females.
I never said that equal treatment under the law was required. In recognition of that fact, I recommended that the GOP offer a constitutional amendment to effect that change. More theater to counter the DEM theater.
In reality, I would prefer representative apportionment. Taxes are based on prior year spend, divided down to a per Senator and per representative amount. Each state is then taxed for their senators and representatives. States get to decide for themselves how they will collect taxes to meet their obligation. States are prohibited from paying salaries of their elected officials until that federal obligation has been paid. That would also require a constitutional change.
If a state wants to tax one group of citizens at a punitive tax rate, they can do so. Others states might tax land ownership, or corporations, or trusts or sales or something else. Each state gets to tax what works for them.
However, the power to tax is the power to destroy. Tax one thing to heavily and that one thing will leave that state.
