Im hoping this isn't false, and wasn't just created to give some people the impression he liked Harry Potter a little too much...

As for kids not knowing what gay is, I dont find kids to be anywhere near the same as when I was one. Quite a lot of them know what gay means, and some will throw it around as an insult even at the young age of five.

Children of 8+ usually know what it means if you ask them nowadays. Perhaps it'd put them off Dumbledore, since some children can be a little judgemental/immature/narrow minded.
