Pointing out that your statements are false isn’t an insult. Now maybe if you actually told the truth once in a while. But you don’t.
Alleging that something which I have seen with my own eyes is a lie, is most definitely an insult. You want to technobabble about the distinction between someone who picks up a crack pipe and never puts it down and your oh so scientificly rigid definition of "addiction" so that you can pretend you have a point. I don't have the patience to deal with such a stupid dodge.
