I think everyone has there own perspective and belief system that shapes how they deal with drinking. My own perspective is very much in line with your friends that you mention in your original post. I fully believe that we have 100% choice in all that we do and I also believe that pretty much everyone has a drinking trajectory that may or may not become a problem for them. But that's just me. It works for me and it doesn't bother me that there are folks that don't share my point of view.
