As teased last night, here's a thread on Lt. Worf and cultural context:
Starting from the very basics: Lieutenant Worf appears in Star Trek TNG as the tactical officer of the Enterprise. He's a Klingon, trek's Proud Warrior Race. (the proud warrior race thing has both inherent problems and issues of racial coding, but I'll leave those aside for now.)
Now here's the interesting part, which was implicit but not overt in the show.
Worf's parents were raising him basically on the Wikipedia version of Klingon culture. They did their very best to expose him to Klingon rituals and cultural values, but only with the imperfect knowledge of cultural outsiders. There was no Klingon community on earth they could participate in. They could teach the declarative content and nominal meaning of the culture, but none of the actual texture as practiced.
@shoofle It's real good. Worf is general is consistently one of the most interesting characters :)
When Worf interacts with other Klingons on the show, there's a distinct cultural divide.
He's been raised with heavy emphasis on Klingon values such as aggression and honor, but only as seen through the filter of Federation (i.e. 1990s american liberal) values.
As practiced by native Kilingons, Klingon cultural values are expressed very differently than how Worf understands them. This frequently catches him by surprise and makes him feel like an outside.
