I'll say why I am. I don't even know what it's like to be under the influence of alcohol...and I love it. The type of social situations with a bunch of people laughing and tipsy is repulsive to me. I have been to a few such situations and it is universally a waste of time.
I'm not saying you should get that experience. Better for you if you continue your abstinence. But you should probably check your attitude when discussing things you have no experience with.
