In fairness, you guys have a pretty similar stream of logical fallacies and misinformation on this topic. I can't blame him for confusing you.
I'm betting they are the same people posting from the same IP. I find it unlikely two people could share such a impenetrable level of hard headed blissful ignorance about a subject they so passionately debate. If you are incapable of seeing any level of understanding in another's position, it is highly likely you do not fully understand the subject.
That said, I understand the argument for prohibition. I am not in agreement we should lift it across the board. Some substances have a more substantial impact on society. My though tis the current policy does more harm then good.
One of them ^ argued against decriminalization in one post... and suggest writing tickets for possession in the next. That is the rule set decriminalization policies nationwide have typically followed. So I don't even think there is a low level understanding of what it is they are discussing.
