I tend to agree with you, Haraka, but these events are probably just a reaction to the years of oppression which (male ) homosexuals have been subject to. Dont forget, it's not that many years since homosexual acts even between consenting adults were illegal. I'm sure we dont need to be reminded of the shabby treatment of Alan Turing, probably the greatest mathematical brain of his time and a massive contributor to the allied victory, who committed suicide in the aftermath of a prosecution for a trivial offence. One could go on, but the point is that male homosexuality was a crime in our lifetimes, and it seems churlish to deny gay people a chance to rejoice in it for the time being. Once it becomes universally accepted I am sure these events will just fade away.
Personally I find gay pride marches rather silly, but as I posted above, I have similar feelings about Wimbledon but I don't want it banned.
