That's true. Psychology experiments attempting to understand homosexuality. This was back in the era because woke took over and homosexuality was still regarded as a mental disorder. Part of the evidence for that assessment was that when straight men viewed pictures of PDA (public displays of affection, ie hand-holding, cuddling, kissing, etc) of women, they focused attention and often became aroused. But when they viewed images of homosexual PDA, the response was dramatic. It wasn't just acknowledgement, it was disgust, and sometimes included physical symptoms like nausea. This is a very powerful response that was assessed to be associated with the so-called "lizard brain" that is thought to have "hardwired" instinctual responses intended to help keep you alive. The studies were understood as a demonstration that straight men not only recognized women and aggressively preferred them, but they also strongly rejected men as romantic partners, naturally because such behavior is maladaptive and does not lead to reproduction.

Of course, you can't say that today. You'd be branded a bigot for having a completely normal and natural reaction.

Hell of social pressure to get you to deny your very instincts, isn't it?
