That's a decent argument if the facts support it.  However, the article states that Bearden was a top amateur male, and the top amateurs race with the pros so he was clearly on the same level as top-tier domestic male riders.  The only meaningful difference between pros and top amateurs in the U.S. is the level of sponsorship and the team's decision to go pro.  It looks like she is a pro mainly because she developed a transgender awareness-oriented team with that level of sponsorship.

Also, she's not winning every race or smothering the competition.  Unless she starts dominating the women's peloton or there is a proliferation of transgender athletes dominating the races, I don't see a major change in the near future.
