Drinking is fun - of course it is, humans, even animals, have made grog and enjoyed the feeling for Millenia. Look at pubs, the wine industry, night life, booze cruises etc. those who think enjoying alcohol is unusual, weird, signs of dependency or a moral failure must not have met many people.
Yes, it's not healthy, addiction/dependence is a huge problem and drunk behaviour can be problematic. But most people who drink, enjoy the physical effects, the taste and the sense of occasion. It does enhance good times because of the physical depression of your system - if you don't like that feeling or chose not to drink, fine, but pretending to not understand the appeal of alcohol to other people makes you look ridiculous - try looking at the wide world, many humans love it. They can go without easily but "vices" can be fun and tasty!
I don't drink anymore due to the calories and the hangovers but I've had awesome times drinking - bonding, laughing, being silly - am I a defective human because it helped with relaxation, enjoyment and confidence at various occasions...probably yes, but so what - I enjoyed it and any other ways to give the same effect (a different childhood, support, therapy, a different personality etc.) were not available!
If it didn't give you those lovely feelings, no one would bother with it so trying to make out enjoying alcohol is completely alien and incomprehensible is disingenuous and cringeworthy.
My old horse bloody loved a beer each night in his senior years (vet advised) - should have signed him up for AA.
