Reader 2, one option is to send back a neutral reply later, appended to his tipsy tirade. Seeing his own vitriol while sober might inspire him to change — though it also could make him vengeful. Another option is to present the emails (which you should be saving copies of) to HR or the association's governing board. They might force him into treatment — or could prove to be a system of enablers.
Hiring a lawyer won't likely help unless you have proof he's picking targets based on race, gender or the like. Sad to say, unless he wants to stop being a jerk, or his superiors are willing to make him stop, your remaining options are "hunker" or "flee."
