Actually, it's a pretty apartheid law. Apartheid means segregation. This law does not harm other religions but it still inflicts apartheid rules where everyone can only marry people of their own religion. That's religious apartheid. It's not a discrimination law - that's true because no one is discriminated against but it is apartheid, because it prevents people from other religions to marry - that practice they execute for in Saudia but is a common thing in all the Western countries where they don't think that the government should tell people who to marry or legally separate religions.
