I don't like the term "character defects" and the way it's overused. Human beings are not defective. Everyone has shortcomings whether they're addicts or not.
I'm also not a fan of calling myself an addict or alcoholic. I know I have issues with drinking. I don't need to announce it every time I introduce myself. I attend a meditation recovery group and most of the people in it also go to AA. I am usually the only person who just says "Hi, I'm readerbaby" without a "and I'm a ________". I just don't find it necessary or productive.
