Out of curiosity, how do you feel about "bong" shops? Does anyone actually believe someone is going to smoke tobacco in a water bong? At least, 99% of the time anyway. But yet "head shops" are legal. Why is "copyrighted" material special? Why does it get protection of "could be used for.."
Disclaimer: yes I know weed is now "legal" many places, but the analogy still holds.
