What is their rationale? We have alcohol and nobody believes that should be illegal. If one is for freedom and liberty one is supportive of legalization.
Bingo. The church ladies failed with alcohol, so they went right for marijuana. Gotta stop all this fun people are having.
That's just not true.
Marijuana was not a criminal offense until nixon.
There were countless hippies protesting outside the White House during his presidency. Mostly against the Vietnam war.
There was nothing legally that nixon could do to get them off the White House grounds. He noticed many of them were smoking marijuana. He had it reclassified a schedule 1 drug and a felony. So he could then have them arrested and removed from the White House grounds.
So if you want to be angry with someone, be angry with nixon. He's the guy who is responsible for marijuana being a crime.
