Mate, I think men beating up on women is reprehensible. But nothing I've read makes it explicitly clear he was a serial offender - which makes me wonder about the part alcohol might have played.Well it allegedly happened multiple times, so I’d say yes it happened multiple times. He’s a maggot that hides behind a drinking problem.
He was evidently arrested (and ultimately found innocent) of another incident where alcohol clearly played a major part. I just thought you may have had some more information to prompt you to call him a maggot.
