Here's an example of what I'm talking about:
Hey, what do you get a black man for Christmas?:
Poster 1: Get him a basket ball, black people LOVE basket ball!
Poster 2: No dude, get him some basketball SHOES! He will love some basketball shoes!
Poster 3: Yo, get him a derby hat. I'm sure that he doesn't have one, and it would go great with his suits!
Poster 4: Shut up poster three, you are useless.
The others gave very steryotypical answers that the initial poster could have found himself, without the aide of others. Hell, some of the replies were down right racist. Poster 3 gave an answer that took SOME level of thought. In fact, he included pictures that can easilly be traced to places where you could find and purchace the items in said pictures. See, in that example you would be Poster 4. Note that poster 4 did not contribute in any way to the aformentioned thread. The irony is that HE is useless at that moment. Well, actually the point of Poster 4 is just to show how useless YOU are. Damn, there goes my whole example. Well you get the point.
