This. Women are not equally represented socially, statistically, or culturally. There is absolutely no scientific evidence that men have some sort of biological advantage to make them better at moving a mouse and pushing keys. This isn't basketball or something where we can measure that men can simply jump higher and run faster.
Even the argument that men have better reflexes doesn't apply because as noted, there are plenty of top 500 women support players and that requires good reflexes as well. Mercy needs to react quickly to being picked and Lucio is basically all reflexes.
Just because there is a lack of women, doesn't mean they are not capable and to imply it, is reckless and stupid. We should encourage everyone, including women, to put in the time and effort to reach top levels because it's possible.

Side note: they are not "females". They are women. The word female denies them their humanity. Dogs and horses are female. However, human females have the distinction of having their own word that implies humanity.
