If someone told me they used to be an alcoholic and completely quit alcohol, I'd have nothing but respect, but this is not what these people are about. What is the problem with people deciding not to drink for philosophical, religious, psychological or other reasons? While I embrace the philosophy "try anything once," I have a number of friends who don't drink for a variety of reasons and it doesn't impede my ability to enjoy their company or respect them as people. Their motivations are different from mine, and that's okay.
