While researching the previous article, I came across this hilarious quote:

This is a far cry from 1966, originally the Klingons were scotch tape Asians (Fong, 176); White actors given slanty eyes. The Klingon race incarnate all the characteristics that most scare White America. The Klingons are violent, ill tempered, lustful, and drunk. They are on a mission to destroy the peaceful Federation and take over the universe. Finally, they fight to the death preferring death to defeat or capture. One scene from an episode entitled The Trouble with Tribbles almost mirrors a scene from the 1944 film Dragon Seed. In both scenes the evil Asians show up at a restaurant and demand liquor, when they are denied they go on a violent rampage. Often, they are shown eating large hunks of meat off the bone Gengis Kahn style.

I’m so going to have to do this at the next geek event.

Clearly Capt. Koloth would be much scarier if he were darker, but apparently demanding liquor is scary enough.
