It was no bombshell. It's right in the open in the last book.
Never necessarily said Hogwarts was Catholic, I just used that as an example of an English boarding school type that couldn’t have used homosexuals as the heads.
As far as “right in the open”, yeah, I don’t know about that. All that spoke to me was that Dumbledore placed a lot of trust in Grindenwald and got burned for it. Obi-Wan also was like that with Anakin as well, heck, Anakin to Palpatine, for that matter, last I checked, both those guys were heterosexual.
