How do you suggest “un-normalizing” it?

It’s a natural urge. Trying to ban it by law or religion is about as realistic as banning people from breathing out of the mouth instead of the nose.

Trying to make it culturally unacceptable also won’t work. It’s already culturally unacceptable to pick your nose and eat it, but some people still do that too whenever they think nobody is watching.

You’ll find that countries that have either banned it or made it unacceptable have much higher crime rates including rape.

That’s how illegalization generally works. It only creates more illegal situations, because it surely doesn’t stop people from doing it.
