The fact that you frame "affirming your identity" as such a pathetic offering shows how little you think of LGBT folks in this context tbh.
Look, I get the anger, but keep your sentiment pointed in a way that doesn't imply that gay people are the enemy soaking up valuable time and resources, or at least listen to us when we say we're uncomfortable with you painting the symbols of our self-determination as cheap tokens to be eschewed from leftism if it wants to help people.
The rainbows aren't hurting anyone.
