Do you believe it is fair to let her compete with “normal” women?

Yes. Michel Phelps is also generally gifted should he be penalized? She meets the criteria for Olympic boxing. Any other statement is revision. I’ve read she has ten losses to other woman. Check how many Muhammad Ali or Mike Tyson have lost. Sucks for the Italian women.

if she have testicles or her body produce testosterone as a male, does…

She doesn’t, so that is not a relevant hypothetical. What if the government is stealing the dog shit from my lawn for research?
