“Your right doesn’t supersede everyone else’s right.”
By allowing her to compete in the women's division, they are taking away the right of every biological woman to a fair and equal competition.
I understand that Lia Thomas would no longer be able to swim with the men. She'd get crushed. And mentally I suppose it would be tough on a person who wants to be a woman to force her to swim with the men anyway. So yes, it is sort of harsh that by being transgender she does not have a class to compete in right now. This is unfortunate for Lia Thomas and I guess if people weren't so obnoxious about her, I might even feel sorry for her.
Lia Thomas is one person who is part of a minority.
We don't solve her discomfort by trampling on the rights of everyone else.
