I think there are effectively universal moral standards, which essentially nobody disagrees with.
A good example: “Do not torture babies for sport”
I don’t think anyone actually rejects that. And those who do tend to find themselves in prison or the grave pretty quickly, because violating that rule is something other humans have very little tolerance for.
On the other hand, this rule is kind of practically irrelevant, because almost everybody agrees with it and almost nobody has any interest in violating it. But it is a useful example of a moral rule nobody seriously questions.
