I don't know, this is what you wrote.
What I wrote was that the only thing that is wrong about marijuana is that it is illegal. Just as the only thing wrong about driving without a license is that it is illegal. Or the only thing wrong about riding a motorcycle without a helmet is that it is illegal. There are a lot of things that are wrong and the only reason that they are wrong is because they are illegal. Just because something is illegal doesn't make it wrong.
During prohibition, drinking commercial booze was wrong because it was illegal. After prohibition, it wasn't wrong to drink commercial booze because it was legal. Same product, nothing wrong with it, before or after.
