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.
