It’s because if a man is victimised then we don’t need to convince other men that they’re a person and didn’t deserve something bad happening to them. I’m not advocating for feminists to speak about men’s issues (they already do though). I’m saying that women are more often dehumanised which is why some people think they need to specify that a victimised woman is someone’s daughter/sister/mother/etc. The person I’m replying to is rejecting the assumption that dehumanisation of women takes place.
