I don’t like being made to defend anything UAE does, they’re a corrupt dictatorship with racism and classism. But blaming any of their idiocy on religion is stupid; the rulers don’t follow any of it and they’re secular because there’s nothing in the religion authorizing their behavior.

Islam grants specific minimum human rights; and women are enshrined some specific rights like the right to their own property and who they choose to marry etc. Other religions lack these, so a Muslim woman marrying into a non Muslim family can’t be guaranteed those protections as well as the worldwide custom that the husband choose the religion to raise the children (this is in all cultures and religions), so as a result of all these reasons it’s considered a sin as well as a bad idea for a Muslim woman to marry a non-Muslim man. Its a reality even if you find the de facto reality distasteful.
