Sports or jobs, it all sets a precedent in society. Imagine if some people said it's unfair certain professional sports like basketball are dominated by black men and unfair to Asian and white men, so there should be two separate leagues citing studies on physical differences. Or if people used statistics to say that since men, ages 18 - 25, from a certain race commit almost half of all violent crimes and murders they should be singled out and profiled. Using scientific research and statistics to make shifts in society is dangerous and problematic.
This is why the TSA checks everyone for potential terrorism at the airport even though statistics say the overwhelming majority of airplane terrorists were males from Middle Eastern backgrounds. Feminism ends where women start to believe they should have special privileges over other oppressed minorities.
Now you’re all over the place. How on earth are you talking race? A black man and a white man as well as an asian man all have one thing in common: they are still men. Their skin color isn’t going to give them an advantage over the other.
However, transwomen are still biological men. The amount of hormones someone takes doesn’t make one equal to your average cisgender women. It’s no where comparable for a person who was born a male to compete against people who were born females.
Again, you’re changing the subject by bringing up random things. TSA checks everyone especially Muslims (no matter the race) because of stereotypes. But stereotypes does not equal scientifically facts. We are talking about sports, my friend. Biological men cannot compete against women, what makes you think that it’s fair for a transwoman to play against cisgender women when they’re two completely different people?
