I agree with your reasons for not drinking. I do disagree with some of your reasoning though.
It seems like you are judging drinkers in the same way you want drinkers NOT to judge you.
It is possible to go out drinking with friends and have a good time without being a dickhead and drinking until the point of spewing.
It kind of sounds like you are saying - if you drink you act like a fool and I don't want to talk with you.
I like to chill out and have a couple of beers and relax. Does that make me insecure and dependent on drinking to have a good time?
Interesting discussion though. Congratulation on staying sober. Stick to your guns!
