Occupy Wall Street members marching to support LGBT equality.
I (David) liked their banner because it pointed out that this entire parade commemorated an event which was considered to be a riot.
I was there, all three nights, and it certainly did not represent prople "working within the system to achieve credible change".
Even a few years ago there were consevative gay 'leaders' who felt that the push for marriage equality was a 'political mistake'.
Personally I don't think it is ever a mistake to demand equal rights.
