supply is never an issue, USA would supply poison to entire planet if the demand was there. blaming Mexico for the sickness of our society is very rich (but often repeated)

I never pretend supply is a monocausal issue, but it is a contributing issue.

You prefer to believe in monocausal scapegoat mechanisms? Stick your head in the sand at your own peril.

You claim US would supply the poison with pleasure itself, but then why is it being imported?
