I've known quite a few CofE/Anglican/Episcopalian priests over the years (in New Zealand, Scotland and England) and I'd estimate that more than half of them were gay.
Based on what?

Based on them telling me. You can be a gay priest in the CofE (in the places I've lived, anyway) without anybody being very bothered about it. And that's been the case for decades.

Seems like a high percentage to me, but I'll take your word for it.

Peace, Mooh.
