But also a true one.
I don't like analogies, but I'll make an exception in this case.
It would be nice if you did not resort to idiotic analogies but so be it.
Massachusetts cannot enshrine slavery in her constitution because the 13th Amendment of the U.S. Constitution prevents it. There is nothing in the U.S. Constitution pertaining to pot.
Aah but idiotic analogies aren’t the only arrows in demojeff’s quiver - he also has half-witticisms and gross distortions. Just ask him.
There is something in federal law pertaining to pot - it prohibits pot smoking for recreational use. And it prohibits most people from growing, possessing, and selling pot.
But California decided to defy federal law with its “legalization” of recreational pot.
How can that be? Simple. California did it knowing progressive Obama and his crew would not challenge the defiance. Obama was a drug user himself - in the past . . . wink, wink.
Will California continue to get away with defying federal law? I don't know for sure. Attorney General Sessions has made some noises but Trump has so many battles right now he may not want to wade into that fight with California, several other rebel states, and the Hollywood/fake news cartel.
As I have said before, progressives will ignore plain federal or state law when it is in their interest and usually they pay no penalty.
But they will stick a bayonet into a baker quicker than they will put a nickel in the jukebox if the homosexual cupcake production quota is not met.
