Most people think kids are cute. They are not sexually attracted to children. There is a difference between the parental instinct and a sexual desire for children. One is the instinct to protect the child from danger. It's the common mammalian instinct, any mammal is genetically programmed to care for the young.
I don't see much sexophobia here, I think it's partially biochemical. The problem I have is that the children can't concent to sex. They can't protect themselves. At least gay men can seek out gay sex from willing parners.
