Right wing queer people aren't invalid in their identity, they're just shunned for aiding people who will oppress all of us. Blaire White is a valid woman, but she's not welcome at pride because she works to make our lives worse for short term gain. Bernie Sanders is cishet, but he's welcome at pride for being a long time ally of queer rights.

Pride isn't for queer people by virtue of their identity; it's for all people that fight for our right to proudly exist.
