"Let It Snow" basically says, "Hey, as long as I get laid today, who cares about a potentially nuclear winter?" Spoiler alert: You will when you get your heating bill and realize there's a widespread famine, you selfish prick.
We made slavery illegal a long time ago. We fought a war over it. So begging and pleading and wailing to another human being and demanding they do your bidding for Christmas is pretty sketchy.
