You may have hit on something with that time period of the '80s.
I think perhaps an important event changing attitudes in the '80s was AIDS.
About mid-decade the assumption of
Gay=HIV-infected simply confirmed and supported homophobes worst fears about homosexuality, and triggered the spread of the regression to extreme right-wing views associated with what was previously becoming a minority during the sexual liberation of the '60s, '70s and even early '80s.
Seems like that regression is culminating now with disparate cultural phenomena from the
birthers and
death-panelites to the dropping hemlines on men's shorts that started with insecure young urban blacks.
It's as though the entire country accelerated toward some safe cocoon with 9/11 - any port in a storm?
Or am I stuffing a bit too much into those tiny speedos?
