The list of demands are here, and they are ... wow. Essentially, the groups wanted to turn Pride into one long joyless religious ceremony.
One of the demands is that the Edmonton Pride Festival gives the activist groups making the demands $20k each so that they can attend diversity & inclusion training across the continent.
"Historically, Pride hasn’t been a time where we honour those that fought before us" Hmm, no, I guess the gay men who founded the Pride tradition never saw their friends and lovers die en masse or anything.
