But as reported on Queerty, the question did occur to "tiny gay tati // 8" who on Dec 16, 2014 used twitter to ask Rowling:
"do you think there are a lot of LGBT students in modern age Hogwards? I like to imagine they formed an LGBT club"
Just minutes later, J.K. Rowling responded with this:
"If Harry Potter taught us anything, It's that no one should live in a closet
...But of course."
That's a sequel I'd love to read!
