Honestly?

Because there are no Trans people. We're getting bothered by about 0.032 percent of the population. (I know the official numbers are larger, but most of those are honestly inflated, claiming other things are trans that truly aren't.)

Even if it's one percent, a vast number compared to reality, how many people will that be in women's cycling? Six to ten for the entire United States?

If they could only compete with other trans women, there would be one race per year and no one would notice it happening.

Besides, if trans women can compete with regular women, they have a much better chance of winning.

Feminists have done this. Let them deal with the fallout?
