"Pot smokers are aggravating" is, frankly, a very stupid reason for anybody to support criminalization.

What? Like, films such as Reefer Madness were created at the height of the anti-marijuana propaganda drive fueled by strongly racist rhetoric to stamp out minorities. That drive and rhetoric dictated US policy for over 50 years, resulted in increasing penalties against marijuana users and leads up to the current day where it's still classified as Schedule I drug.

Your framing of the situation is just remarkably wrong considering the entire legal history of marijuana in the US.

Your comment kinda demonstrates his point though. He made a comparison, and you pointed out that what he compared weed consumption to is crazy. And you said absolutely nothing about weed consumption itself which is required to understand the validity of the comparison. And not providing that part is exactly demonstrating the lack of self-awareness.

His comparison was between your average smoker arguing for legality vs an entire institution that was setup to criminalize and demonize them for decades, then calling them equally a problem. What exactly here would change the validity of the comparison?

At least claiming that your average smoker arguing for legality would provide more substantiated arguments, than the institution in question.
