When you profer drunkenness as an apparently sincere excuse for appalling behaviour, you're saying two things:
1 - You get drunk a lot.
2 - You, your family, and your friends all accept heavy drinking. Drunkenness is part of your lifestyle and probably theirs too.
There is something seriously wrong with a culture that accepts habitual drunkenness.
