This argument is somewhat undermined by the inclusion of Japan, a country well known for just how debased its porn is.

Laws are not a good proxy for culture. Culture is only one of the inputs into a country’s laws. Frequently the people who make the laws are not the same as the people who have to follow them.

As for Islam, Christianity and Islam are closely related, both being Abrahamic religions. I don’t think a distinction is meaningful in this context because both the Bible and the Quran include same story of Sodom and Gomorrah, so their sexual morality comes from exactly the same Abrahamic tradition.
