ROTFL - I notice you omitted it AGAIN!
Do you support the legality of alcohol and tobacco, and if so, are you thereby promoting their use?
I don't try to justify bad behavior by pointing out other bad behavior,
Nobody's asking you to "justify" anything; your opinion that the use of alcohol and tobacco is "bad behavior" is noted (and I agree that it's behavior that's best avoided). You haven't addressed the question ... let's take it one step at a time:
Do you support or oppose the legality of alcohol and tobacco?
nor do I engage in Moral Equivalence arguments where none exists.
The only "equivalence" being proposed is that support for legality doesn't imply promotion, whatever the substance in question.
Do you support or oppose the legality of alcohol and tobacco?
I don't care one way or another because the reality is they are legal and have been for all of my life.
I started smoking when I was 5 years old that would have been in 1943, I would not recommend it. My first alcohol came from a still my uncle ran in the Cookson Hills, in 1951, I don't recommend that either.
