You might be right and ultimately it's a person by person thing. But in my not-so-scientific search that doesn't mean that much of anything but that i found interesting through posts on the board that include the word (this took me about 6 minutes, so not grasping TOO much at least), in the last 6 months ish when talking about individual people here's what I saw on huskerboard:
13 references to blacks as 'thug'
2 references to whites as 'thug' (Incognito and Raiola)
and about 300 references to Miami
So does that makes us racist against Miami when we call it Thug U?
Course not that's the name of their prison yard
