There is enormous cross-cultural variation in the way people behave when they drink alcohol. There are some societies (such as the UK, the US, Australia and parts of Scandinavia) that anthropologists call “ambivalent” drinking-cultures, where drinking is associated with disinhibition, aggression, promiscuity, violence and anti-social behaviour.
There are other societies (such as Latin and Mediterranean cultures in particular, but in fact the vast majority of cultures), where drinking is not associated with these undesirable behaviours – cultures where alcohol is just a morally neutral, normal, integral part of ordinary, everyday life – about on a par with, say, coffee or tea. These are known as “integrated” drinking cultures. This variation cannot be attributed to different levels of consumption – most integrated drinking cultures have significantly higher per-capita alcohol consumption than the ambivalent drinking cultures.
Instead the variation is clearly related to different cultural beliefs about alcohol, different expectations about the effects of alcohol, and different social rules about drunken comportment.
