Well, yes, that makes sense, but they're essentially advertising that they had limited empathy for 50% of the world population until they had a daughter. It's a bit of a shit admission and they shouldn't be lauded or congratulated for their very belated awareness.
I concur.
I also thought the article wasn't bad and made a good point. As I've posted before, I talk to my dad a lot about feminism and issues related to it and one of the things I've said as well is that I wouldn't want him to care because of my existence (as the article was speaking of, because he has a daughter). I'm glad I'm able to raise these issues to him and that he listens and engages but he (and others) should care because women shouldn't suffer misogyny, not because one woman shouldn't suffer misogyny and in a world women do it's highly likely she will. That said, I understand the value of maybe personalising feminism to men who might not otherwise register how important it is and making them consider certain issues with regards to their daughters if they have one isn't something I'd completely dismiss. However, as the article deals with, this implies other men should/will be oblivious, dismissive or not care at all about misogyny and discrimination against women and girls. The "if it was your daughter" line suggests misogyny only matters when it affects their own offspring, that it was fine for every other woman or girl to suffer it but not for her. This I don't think really works towards truly combating misogyny and misogynist attitudes.
