and re-reading the snippet you posted, I would disagree that it does disparage women, gays, The Entire Continent of Africa
It talks about the gender paygap (ugh, not a thing), colonialism being responsible for Africa's ineptitude (interesting idea. I know the western fashion is for full on mea culpa regarding Africa, but I'd like to hear more about this), children doing just as well when brought up by single parents (as discussed above, RL is correct that this is wrong). He also talks about gay parents, I'm afraid I don't know the details here.
These are just ideas. They are ideas you clearly disagree with. But I don't think that means that no-one else can engage with them.
