I'm gonna handle the Laurel Hubbard thing before the Olympics happen because we all know what's gonna happen if Hubbard doesn't win gold - "Well, you see, Hubbard was beaten by cis-women. Any objections to Hubbard competing as a woman is transphobic."
No, that's not how this works.
Hubbard is 43 years-old. That's twenty years older than the average for a cis-woman competing in that category. Yeah, Tom Brady is the same age and he's still great; but there are a lot of caveats. The quarterback position isn't entirely physical; in fact, most of the Hall of Fame quarterbacks that we've had sucked at the age of 23. Tom Brady is also still regarded as a freak of nature while competing against other cis-men. Weightlifting requires skill and technique; but, I can tell you from experience that it doesn't require you to strategize in a matter of seconds. The fact that a 43 year-old even qualified to compete with 23 year-olds should tell you something.
Okay, that doesn't convince you that something's wrong here because Fallon Fox was beaten by a cis-woman.
Bad argument. Fallon Fox sucked at the sport and wasn't on the MMA radar until the transition. Fox was winning by brute force. Ashlee Evans-Smith knew what she was doing.
Not good enough?
Okay, simple - name one trans-man who has even been competitive in cis-men's sports. Trans-women are constantly and consistently breaking records in women's sports. There are no trans-men who are even making the team.
Being politically incorrect is protecting women in sport. Being politically correct is banging your hands together when you see biological women get their skulls cracked open.
