I don't think it was lies per se, they just talked out their ass. And for a time in the 80s, it really did whallop the straight community. Nothing like it did to the gays but it was an epidemic in many cities, due one dude shooting up and getting it and then fricking a bunch of woman. I think most of that curtailed with needle exchange programs.
It was an intentional lie re: studies. And it was designed to scare the straight community.
Go back in time. In the mid 80s Jerry Lewis was raising tons of cash for Muscular Dystrophy. Why? Because before that tons of cash was raised by March of Dimes, founded in 1938 to wipe out polio.
Well, polio got wiped out by the Salk vaccine in the early 50s. I ate the sugar cube. And if you know what that means, I'm impressed.
Jerry tried to replicate it. Didn't work except for making tons of cash for the non profits.
AIDS advocates at that time wanted the same treatment. They knew they were not getting donations like that because AIDS was viewed as 'self inflicted' as opposed to Polio or M.S. So, they tried the 'Break Out' scare. Everyone will get AIDS, so you better lobby your Congressman for more money.
