Well I am sorry you find it rude but the woman has been on my back for 2 years making snide little comments about everything so in my eyes she had it coming. If you mess with the bull you get the horns. I don't have to justify my actions to anybody except myself. Was it rude, yes it was. Am I a jerk, 7 letter word that starts with A? Yes I am and I know I am at times. I don't have a filter and if I am thinking it you better believe I am gonna say or do what is on my mind.
As far as apple from the tree...My dad does not drink nor do I it is my girlfriends dad who drinks.
1) I believe it was quite clear that it was not your own father you were talking about but your girlfriends.
The comment I made was in jest but the truth remains that most people drinking a gallon of vodka will end up dead very quickly.
In fact, a pet peeve of mine has been how society has reacted to addiction, generally speaking towards drugs, shunning many addicts and forcing many into lives of criminal behavour due to the hypcrisy of those that consider Alcohol to be better.
It might not grab as many in an addictive sense as lets say, ...... will BUT any alcoholics that continue will most certaily die drinking such large amounts as most ...... addicts will at some point in time. If not from excessive drug use than by their bodies one day no longer being able
to handle the abuse but alcohol in such cases is far worse, yet overlooked.
I think a great example of such was the UK Singer, Amy Whinehouse. The world commented repeatedly about her ...... use and yet it was night of binge drinking that took her down. Ironically to some, not the ....... Not at all suprising to me.
2) The step-mom might be an annoying person. But you chose to tell the story about blowing vapor into her face and by doing so, you must be prepared for the backlash if any. It might have been one of those moments that were best left unsaid and kept to yourself.
But since you did feel the need to bring it up, remember, although free speech is that, free, it does come with consequences and in this case, blowing vapor in someones face that has already shown themselves to have very little patience for it, hurts no one but the rest of us.
It's not the way to win those peope over. Hence it was a rather immature act and I for one would much rather you show your dislike in other ways or, not at all and just ignore her BUT we don't need any more scrutiny from the anti smoking crowd and your little act only goes to create more hostitility towards us. Hence, you brought it up and yes, you are right you don't need to answer to anyone but perhaps you should understand that if you are going to be a dick, maybe its not best for you if you make us aware of that fact!
3) I can't stand anti smoker types especially though if they are fanatical for often they are lying. Those that cough and make choking sounds as if to imply you are stinking of cigarette smells when you really only smell like home baked goods are a great example. BUT if she is living with a man drinking a gallon of vodka and in her own home people are not respecting her wishes about them not smoking or vaping indoors, then I don't blame her one bit for her feelings. I'm with Bruce ad believe you were lucky for not having your face slapped.
I would NEVER dream of smoking or vaping inside someones home that expressed their wishes. It's their home. Not yours and if his daughter was disrectful enough to let you Vape inside although wishes had been made very clear that the step-mom did not want you to do so, I would suspect that there is far more going on with control issues from said daughter being shown her step mother. Who knows? Perhaps she hates her out of loyalty to her birth mother. We dont know but can surmise there is more going on there, hence, my comment, she may not need to divorce him but simply wait for he will likely drop dead soon anyhow, was fairly made.
Bruces comment, that the apple does not fall far from the tree is only to suggest that children end up like their parents far more oftne then they wish to. Many will indeed do everything within their powr NOT to be the parent they detest but in the end, usually end up more like them than they ever thought possible. It's just one of those unfortunate + often uncanny facts of life.
If you don't feel that you need to answer to people, don't leave comments that evoke negative emotion for its not any different than trolls that make comments to anger people and then act suprised when people react.
The bottoom line is that such comments and behaviour tell us far more about you than perhaps we care to know but if so, its your doing, not ours so perhaps its best to remember that just because you can say or type it doesnt always mean that you should.
Now, that was more typing and thought put into it than I had wished for but thought it might help you to understand wy people will react as they do so if you dont want such reactions, then best keeping such comments to yourself.
EDIT:
Interesting. One cant apparently type the properly spelled word, Hair-O-Win although any hard drug could have been substituted by name in this comment.
I was very irritated to hear her say that. She told me to go outside and vape if I wanna vape. I decided why not just go offend her some more since she is already over sensitive anyways. I got up out of my chair and walked over to her and took a big long drag off my stingray x and doge v2 and blew a big fat cloud right in her face 
I'm sure she caught a contact vape.
