Is it an elephant?
Firstly the people in the thread have suggested legalising drugs, bringing them onto a level with alcohol but I don't think anyone is defending alcohol. I agree with you fully that alcohol is as bad, if not worse.
The last 30 years have seen the media and especially films and series promote alcohol as the must have "accessory". Finished work, have a drink, sit down to relax, have a drink, feeling tense, have a drink, going on a date, have a drink, want to be happy, have a drink, dinner with family , have a drink.
People are being conditioned that drinking is not only good but necessary to exist. Commercial marketing's greatest success.
