You’re acting like the liquor is the problem. Alcohol is just a chemical, it’s not a sentient being. It does not change people’s personality, merely exposes it’s layers. People who behave poorly on alcohol are people that behave poorly without it, or if they don’t, they’re so close to losing control that being drunk pushes them over the edge.

Teach your son how to be a good and controlled person sober, and teach him to be good at it, and he won’t lose that when he’s drunk. If that’s something that seems difficult to you, why yes it is, parenting isn’t easy. If that’s something that you think you can’t do, woman up and figure out how.

You won’t win this war if you’re battling the liquor. You will win if you create a personality that doesn’t fall apart in impaired conditions.
