MM is almost an oxymoron. 99% of MM users just want to get high. I don't give a shit, just don't try to make me believe it anything other than that. And like Sluggo pointed out, most potheads will gladly give up other rights just to get high. The truth is both are an addiction.
You said you have met many alcoholic wife beaters and no stoner wife beaters. Basically implying that all alcoholics are abusive and all potheads are saints. Pretty much a blanket statement.
And as far as the messenger goes, I think you're a fucking liar. First you say that you've met many alcoholic wife beaters then you said you know the facts. So which is it? I think you haven't personally met many wife beaters, I think you're just parroting what you've read. So if I'm correct then you are a fucking liar...
