In The Elder Scrolls V: Skyrim, the player has the option to participate in hetero- or homosexual marriage with any of the other playable races, with no judgment from other NPCs. I can't help but think this is only for game mechanics, and that there would actually be some type of discrimination, especially since the hatred between certain races are so strong.
So, my question is, are there any types of laws on marriage in the Elder Scrolls universe? Is homosexual marriage illegal or frowned upon (since there are no homosexual couples present, at least not in Skyrim)? Is marriage between races taboo, especially between Man/Mer and beast races?
