I think when we start to define "normal" it opens the door to the old debate about the definition of alcoholic and associated stereotypes, which can then be used to justify drinking in the context of
"well I'm not like that, or I don't do that, so I must not have a problem" or the disassociation phrase of "my drinking isn't as bad as their drinking, as their drinking causes a whole other level of problems"
The normal things, no matter what they are, are still problems, and alcohol is causing them . . . Sobriety is still a valid way forward!!
