Not a fan of this at all. It's unfair to biological women to make them compete against people who were born men, as males simply have more muscle mass and can maintain more muscle mass even after hormone therapy. We've now seen multiple examples of trans women who were allowed to compete against biological women and utterly dominated them. Trans women should be in a league of their own.
As for trans men, I honestly have no idea how fair that is as we have seen few examples of trans men competing against biological men so far.
Competitions are inherently unfair, especially physical ones. Some people are just naturally born with more athletic features and advantages. Also, considering the harassment, trauma, discrimination, etc. trans people receive, as well as the costs associated with transitioning, the chance that someone is transitioning specifically to have an advantage in competition is miniscule.
Trans men are men and trans women are women.
