The parent isn’t discounting male on male crime, in fact quite the opposite. He was responding to a comment about maybe men need more protection than women.

So your analogy to the police discounting black on black crime isn’t correct.

I'm not discounting male on male crime. The comment was supposed to be a confirmation of the parent's question. The other stuff came out because I learned it while reading that wiki and thought it was interesting, not because I think it's okay to ignore violence against men. (But I understand how it sounds like an implied "they deserve it" argument)

Yeah... intrinsic group characteristics are also used in many arguments you might find less righteous.
