What the…? Marry within their own kind? Are you alright? Sometimes, when I feel like Ive seen and heard it all…people like you surprise me with even weirder things. Do you know how ridiculous and backward you sound?
What exactly is their own kind? They should come stamped with a letter D on their foreheads and only marry those also stamped with the same?
I dont know about your society but Ive never heard of such nonsense in mine.
