It isn’t politically correct, but it certainly acknowledges that there are differences between the sexes. However, everything is context dependent. Like the advantages that women or men have may be more relevant in certain cultures and social contexts than others. From a scientific standpoint it is kind of interesting to ponder the idea (that has been proposed by many scientists, particularly geneticists) that suggests that over a HUGE (we’re talking on an evolutionary scale here so at least in the magnitude of millions of years) period of time, the Y chromosome may just disappear. What I don’t remember is whether certain sex-determining genes are on it or not. I actually kind of doubt it as it relatively inert (lacking in “active” genetic material). In addition, in the past, transpositions have occurred that essentially migrated at least some genetic material from the Y to X. Maybe humans will end up with a genetic model similar to certain other mammals where males simply have a single X if that theory has any validity.
Either way, the science doesn’t necessarily dictate that males will cease to exist, Y chromosome or not. As for social superiority, I have serious doubts about that one. Even in Western countries, male dominance and its remnants are pretty obvious…this clearly isn’t going away anytime soon. Also, he probably stated things in this fashion for exactly the reason you posted this, shock value! He wanted to get attention to some of his claims regardless of how uncomfortable they are.
