For one thing, if they are not alcoholics they don't understand what it means to be an alcoholic. They don't understand that a true alcoholic CAN'T cut back. Or they just don't care and are alcoholics themselves but don't realize it.
Having said that, I'd agree with the others - what they say couldn't be more irrelevant. If you think you have a drinking problem you need to do something about it. If that means getting local support by all means do it- via AA, some other support group or counseling. Or any combination. Bottom line though YOU have to make the decision to quit and act on it - regardless of what anyone else says or does.
