Let me ask the question again.
If the federal government ignores laws, then how could they possibly expect the states to comply with any federal law they don't like?
Or, if the feds can ignore federal laws then why can't the states?
So, if the feds, and the states, can ignore a law, then why not the citizens as well?
The rule of law is important to society, enforce the darn laws or change them.
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
