I don’t understand why everyone believes Grindelwald to be homosexual, just because Dumbledore was gay. One doesn’t preclude the other. It was never even made clear if they were more than friends. For all we know it was completely one-sided on Dumbledore’s part.
I'm just curious about the Dumbledore being LGBTQ+ thing. Why do you find it so aggravating? I don't really see it as a major issue. Just wondering.
