That's prejudice. Alcohol makes people violent and out of control, more so than any other drug, and yet we're the ones that are untrustworthy?
> I'd encourage non-drinkers to at least learn to play along and have some beverage in their hand.
I'd encourage you to fuck off while I smoke a blunt and blow the smoke in your face.
We're talking about parts of human psycology like not having the same posture as the rest of the group. Of course it's prejudice, but it's also real and difficult to be aware of when it's happening to you.
Also, nobody is showering their drink on you if you don't participate, so blowing your blunt smoke in their face is a much bigger asshole move for me.
No, PCP is known to make users violent beyond what alcohol would do. And increased alcohol consumption correlates with less ability to act violently, because at some point the drinker is going to be unable to move, while PCP does not degrade one's motor skills.
