I think it's this bit: "does not apply to all skin colors, genders or sexual orientations"
If he'd said "does not apply to all countries" he'd probably not get downvoted, but the idea that people of different sexes and races don't have equal freedom is a hotly contested political question in many countries.

I think the point is that not everybody benefitted equally. I don’t think that’s very contentious, we can just look at the civil rights movement or even women’s suffrage, both of which are relatively new things. It would seem that the benefits are very slowly evening out though - every couple of decades there is a noticeable improvement. It’s not as fast as would be ideal, but at light speed compared to most of human history (which has been pretty brutal over all)
And yet the history of the 20th century, there are plenty of cases where a society has _regressed_ along this axis. Sometimes quite suddenly.
European fascism is the obvious example, but it's also really interesting to look at the trajectory of social freedom in places like China, Iran, Afghanistan, etc. Progress is not guaranteed.
