There is a ton of academic interest in the relationship between sexuality and fascism. It was first noted in "The Mass Psychology of Fascism" by Wilhelm Reich after WW2. My comment is, of course, a massive oversimplification of a complex social dynamic.
It's the same dynamic that made US racists paranoid that black men wanted to rape white women when, in fact, their deeper fear was that white women wanted to have sex with black men. Fascists are particularly sensitive to sexual relations between "their women" and whomever they have chosen to blame for all their misfortunes.
I know plenty of people with technical smarts and high IQs who regularly fall for disinformation scams. Lots of smart people are as prone to believing what they want to believe as complete idiots.
People with strong intuition often make it through life without ever seriously developing critical thinking skills because they simply don't need them.
