There is no such thing as a “biological woman”, because biology determined sex, not gender. Worrying about “womens safety" from “men in womens clothing" ignores trans men, who also face sexual violence from men (and women, but you dont believe in that). It also demonized trans women, who are NOT men in dressed, so we should be worried about male predators. Not trans people getting legal protections.

No “men" are trying to compete in womens sports. Women (who are on estrogen for a significant amount of time, so their fat and muscle distributions are identical to a cis wonan’s) are.

Also, physical strength is based on hormone balance, not gender.

Many trans people arent on hormones for a variety of reasons, so a trans man with his “natural” estrogen balance would be “weak", arent you worried about their safety in men’s restrooms?
