The backlash on the topic of transgender athletes is incredibly over the top

Every athlete could be measured on the amount of testosterone, as some women naturally have higher levels, similar to men. Does this give them an advantage and should they be banned from competing?

Biological men are said to have a "biological advantage" competing against women, but Michael Phelps also has a biological advantage over his competitors for having a very large wingspan.
