Sports have always been dominated by people who have exceptional biology, regardless of gender. This argument about advantage is unwittingly highlighting the unfairness inherent in competition. We know they’d never go as far as to ban really tall cis men from playing men’s basketball due to their biological advantage, so their argument is garbage.

Then there’s the tired “reproductive biology” argument. If a cis woman gets a hysterectomy, is she then no longer a woman? Obviously that’s not how that works.
