Seriously, who in their right mind would imagine that something so ridiculous was true, especially from Canada? But it was.
In the 1950s, the Canadian government created the so-called "fruit machine" to identify who was gay in order to fire them.
But how did this "gaydar" work? They basically showed images of gay pornography and monitored people's reactions, such as pupil dilation, and if it showed a "gay reaction," it was recorded.
