Kelly, you must not follow local politics if you think that Seattle "does not allow discourse". EVERYTHING on the local level is about "achieving consensus", and that's why nothing ever gets done. They call it "The Seattle Way", LOL.
But we are a city of firsts, both good and bad: First Women Mayor, first place to allow women to vote (although they rescinded that when the women started to clean up the vice) First place to ratify prohibition, first place in the US to play a Beattle's song on the radio, first World's Fair to break even...
On the topic of the thread, we are the first city of offer a counseling service geared specifically to GLBT people. That didn't happen until 1969, which should give the younger folks an idea of the isolation many gay people felt in the previous decades, when homosexuality was considered a mental illness, and cause for involuntary commitment in some cases. Men could also commit their wives. That happened to the mother or a friend of mine.
Employment rights of sexual minorities were affirmed in Seattle in 1973, and the City broadened its housing laws in 1975. That was held up by popular vote in 1978 when some militant conservatives tried to get them to repeal that by initiative. 2/3 of the City of Seattle rejected that.
The 70's was also the decade when Seattle finally started to break the protection racket within the police department that was extorting money out of gay bars so they could stay in business. The corrupt police were working with corrupt state liquor agents, so they held real power over the businesses they targeted, particularly given the obscure liquor code of the time, which said that women could not sit at bars without a man, and no one could be standing with a drink in their hand.
So, you can see that militant leftists have been of some use to all of us. People - including me - may look nostalgically at the clothes and manners and lifestyles (and especially appliances!

)of the earlier decades - although memory does tend to soften things - but don't kid yourself that we haven't evolved. And it took a lot of kicking and screaming to get there. And sometimes it takes kicking and screaming just to stay where we are.
