"Domestic abuser" brings up the mental image of some sloppy drunk bastard in a wife beater who, well, beats his wife. Most women and men cannot seem to grasp that women can be and often are domestic abusers, especially when it comes to abusing their children.
I wouldn't have a problem with it if it was "convicted" and not "accused", but you only have to look at things like Title IX to realize certain moral panics (like the rape "epidemic" in colleges) are enough to overturn the importance of due process for a lot of people. I mean, what are you, some sort of rape supporter or something? Do you love rape? Is that why you want due process for accused rapists? Obviously if someone is accused of rape or domestic abuse they are automatically guilty, you shitlord.
