Male homosexuals have been sacred cows in American culture for so long that some believe that they have a license to engage in extremely offensive public behavior and speech. In this culture, when a straight man sexually harasses a straight woman, and she objects, the straight man is the bad guy. When a gay male sexually harasses a straight male, and he objects, once again the straight male is the bad guy (for demonstrating his "homophobia" and his inability to "take it like a man.") It adds up to a formula for producing fury.

More to the point, it is seen as "OK" for the female to respond violently to harassment by a straight male

Yes, good point. Were the shooter in this case female, and her victim a male who she claimed had harrassed her, she would be presumed to be the true victim, while he would be the oppressor who got what was coming to him.
