That's been there since the first beta patch, and at the time was decried by leftists as a dog whistle for murdering interracial couples. There was even a petition circulated to ask WoTC to intervene and get it removed from the game.

As far as I'm concerned it absolutely is said dog whistle too, a rare example of leftoid making a correct accusation. The smaller race involved in that monstrous gangbang is literally called "bugbears."

Couldn't be more on the nose.
