No but the federal government trying to legislate one’s personal ability to engage in either is not too fundamentally different than deciding what people can and can't eat.
If a free person elects to engage in a life of personal depravity, as far as I am concerned, that is between that individual and his maker so long as his actions are not injurious to others.
This is how as conservatives, we wind up shooting ourselves in the foot over and over. We engage in semantics over where we erect our personal barriers on social issues and are rarely able to coalesce and project a cohesive message.
The left know this and do an excellent job of parsing our inconsistencies and lampooning us on them.
So, if a drugged out person kills somebody, do you support a death penalty, with no possibility of appeal, so long as they were proven to be beyond self-control? Swift trial and execution, how many "libertarians" would go for that?
As to harming others, how about their kids?
