Honestly, most conservatives are just directing their rage toward whatever conservative politicians and talking heads tell them to direct it at. Conservatism lives and thrives on hate, requiring in-groups and out-groups that must be pitted against one another. The new fad is to care about a person’s genitals.
You see, conservatives don’t believe in gender equality, so someone who isn’t a cis woman will always perform better than cis women, because they believe that women are inherently weak and men are inherently strong, failing to believe that any other form of gender identity even exists.
Except here's the thing; I'm pretty sure I've read this athlete has a vagina, and has had one all of her life. They just don't understand sex, and how complex it can be.
