Sure, I'll do the elevator pitch.
The LGBT purge, from the mid-1950s up until 1996, was the systemic discrimination against queer people within the federal civil service, the military and the RCMP. It included investigations, interrogations and sometimes just harassment. Thousands of people were fired from their jobs. Most people, like myself, received an honourable discharge that said, “not advantageously employable due to homosexuality”. It was tied into the McCarthy era. Canada continued it until it was ended by a court case in 1992 by Michelle Douglas.
