Being a member of the LGBTIQ community, I like how they seem to be going in terms of Dumbledore's sexuality in its' realism, so to speak. I'm looking at the history of the laws affecting those who were a part of the LGBTIQ community especially in the UK, you can imagine how Dumbledore would need to have kept his sexuality a secret especially during certain eras in history like World War II.
These views are my personal views if others disagree, then so be it.
