I have an in-law that has a habit of excessive alcohol consumption coupled with a propensity to engage in alcohol induced rage. Suffice it to say that he has said some horrific things about me and my family members while under the influence.
I recently had another less than desirable interaction with him while he was intoxicated and decided to put an end to it.
I once tried explaining his drunken behavior to my sister and she became highly defensive and told me to "take it up with him". Many suspect he has some type of alcohol use disorder, but it is a sensitive topic to bring up. My sister resented my mother for scolding her about his drunken behavior.
I would like to communicate to my sister that my tolerance threshold from his drunken antics has been exceeded and l never again want to be in his presence if he has been drinking or any possibility exists that he will be drinking. But she will most likely defend him and accuse me of being the problem as in the past.
Is there a tactful way of approaching the subject without offending anyone?
