Speaking of Dumbledore being gay. I love the hilariously slightly camp way he introduces himself at Harry's hearing in OotP. 'Witness for the defence Albus Percival Wulfric Brian Dumbledore' its just the way way he says Brian lol
Probably just me but watching it back now we know just makes me think.
There was quite a bit of campness throughout the HP series. I particularly like McGonagall's bitchy putdowns to Sybill Trelawney at the Christmas dinner, and her owning of Umbridge during Harry's Careers Advice
