There are plenty of people who take issue with the often comedic and casual approach towards victimized men in fiction. Most of these are people who believe in the social equality of the sexes.
a.k.a. Feminists.
You were doing well up until this part. There are no groups on earth that trivialize male victims more than feminists.
Running Erin Pizzey out of the country for saying men need domestic violence shelters too? Check.
Feminists suppressing evidence showing almost half of domestic violence is committed by women? Check.
Feminists disrupting various speeches talking about male suicide/mens issues? Check.
And don't respond by saying these people aren't real feminists. They are. How about trying to rid the movement of the bad eggs instead of defending the movement from those who take issue with the bad eggs.
Oh, and there are far more people who believe in the equality of the sexes who don't identify as feminists than than there are that do. They're either called egalitarians or don't feel the need to label themselves. Most don't wish to be associated with a toxic movement.
