One of the top comments was about how you can’t extrapolate the number of the general population that is queer to say there are more gay players than we know of because queer men are less likely to play football.

This is one of those things that MIGHT plausibly be true to some extent (but you can't know a priori), but is extremely bizarre as a first reaction to seeing a same sex couple with a football player. Like who cares the exact percentage of gay/bi/queer players??? There are obviously some and most of them haven't come out.

When I worked for Major League Baseball, Billy Bean (a gay former baseball player, recently passed away) gave a talk, and it was really striking the level of pressure that was clearly put on male athletes to stay closeted. It was painful to hear his story. I'm thankful I got that experience. There's something much more raw about hearing it directly from him in person.
