I'd hope they wouldn't be applauding but if by "defending" you mean people drawing attention to the crisis in men's mental health then yeah that could well happen and in my opinion rightly so, as they are for mothers.
Ironically that series of articles by Sarah Harte the one where she says mental health shouldn't be considered where the father commits the crime she was admonishing Fr. Brian D'arcy for saying exactly that at the funeral of a man who had committed such an act.
So it's completely fair and accurate to say that it would be received differently if a man wrote it about a man, but not to say that it wouldn't be said.
