Those remain merely your straw men: nobody ever said nor implied that you think tobacco is good, nor that it "excuses" anything.
The point is that if one makes arguments regarding marijuana that also apply to tobacco, others are entitled to explore their application to tobacco - and do NOT thereby deviate from "the actual topic of discussion."
I never said you, or anyone, can not use marijuana..or whatever.
just that if you do..
ACCEPT the consequences.
That is at the heart of libertarianism,right?
You have the right to do almost anything you want as long as it doesnt harm someone else.
That includes not making other people pay for any consequences of ones choices,right?
No libertarian supports making other people pay for any consequences of ones choices, nor do I; they and I oppose government programs that do so.
It would be anti-liberty to say that because such programs exist, marijuana or tobacco ought to be banned.
We agree.. marijuana should not be banned.
