There are an awful lot of non entitled men in this country, decent peaceful men who love their partners and families, who don't kill, who don't abuse. I'm mother to a son and would be horrified if someone was automatically assuming awful things of him, same with my husband and some of the lovely guys I know, who also happen to come from minorities as well.
Some men grow up with problematic models of masculinity, not all.
You are also saying that all the friends and family of the wife were so uncaring they they just didn't listen. She may have not wanted to speak openly about the problems in her marriage or indeed did not think her husband was a threat.
