The truth is
In February 1972 the National Coalition of Gay Organizations met at the Armitage Avenue United Methodist Church in Chicago. An invitation had been sent out to 495 homosexual organizations across the U.S. to come and prepare a "gay stance for the 1972 elections."
About 200 individuals from 18 states representing 85 organizations showed up for the two-day event. Conference participants adopted the 1972 Gay Rights Platform, which included 17 federal and state "demands."
One demand is (Federal):
Federal encouragement and support for sex education courses, prepared and taught by Gay women and men, presenting homosexuality as a valid, healthy preference and lifestyle as a viable alternative to heterosexuality.
