So let's be hypothetical instead. A disproportionate number of players in the NBA are black. Rather than explaining that the good-ol' fashioned racist way, which emphasized physical abilities inherited from surviving the middle passage (or some nonsense), we now generally agree that 78% of NBA players are black because basketball is a big part of youth black culture. It's an important part of socialization in much of black culture, blah blah blah, so that explains that. The same goes for why 90% of professional golfers (I'm making these numbers up) are white, right?--it's a part of white culture; it's not that white people are genetically predisposed to the golf swing.
But IF (!) there is a disproportionate number of gay men in Olympic figure skating, how do we explain that? Most of the Olympians must've started skating long before they were comfortably (or uncomfortably) influenced by gay culture. Whereas black men are habituated within black culture from the time they can walk, gay men are seldom raised "within" gay culture--most of their parents are not conversant with gay culture. So what's going on here, hypothetically?
What explains it?
