Why is appropriating gender okay with the Left, but not race?

Ryan blows apart the foolish notion that males can simply declare themselves females without any regard to inherent biological differences that cannot be changed in humans any more than they can be changed in any other mammal in the animal kingdom. The Left's mental gymnastics on this issue strain credulity, shock the conscience, and insult our collective intelligence. The U.S. Supreme Court heard oral arguments on Tuesday pertaining to two state-level cases where Idaho and West Virginia passed laws prohibiting trans-identifying individuals from participating in girls' and women's sports and spaces.Title IX was designed to protect XX chromosomal, biological females in the public sphere. Not males identifying as females. Why is the Left okay with this type of appropriation, but averse to a Rachel Dolezal appropriating race as a black woman?See omnystudio.com/listener for privacy information.
