So, let's try to pull context out of this:
1) Racial minority upset that development group said that "race doesn't matter" but stomps over that with "the character is white because it's relatable". ~~~~Yes, that is racially ignorant of the developers to say. Can't have it both ways, it's one or another: either race does matter because you're targeting a white audience, or race doesn't matter and the nothing is relatable at all, which means the character can be black/white/Latino/whatever.
2) Enter 3 challenged white, heterosexual males with an ignorant statement of being a "minority". And blame Obama for it as well ~~~~Last census in the US still showed 'whites' as the majority (though estimated to change by 2025). Furthermore, the lauding that sexuality or sex separate one's self within their own "racial group" is absurd. I guess this joke is created by the simple fact that white heterosexual males are threatened by female progressiveness, homosexuals, and minorities all at the same time. Funny because it's true. Also, Obama has nothing to do with it at all....just a scapegoat for them to blame self delusional issues on.
3) "Sup, baby. You 'mirin?" ~~~ An emphasis made to assert that these "lunks" only see females as sexual objects that admire their physical presence.
4) Friend Zone/Son Zone. ~~~ I honestly don't quite get the context of this joke. I'll throw a guess that "son" is the white Jersey version of saying "homie", where as "friend" is like in the context of a common word similar to that of Candians use - ex. "Hey, friend". Maybe I'm misunderstanding the joke because I'm not tied to the MTV sewage subculture? I hope that's the reason.
5) "Zimmerman Mode" ~~~ You really went there? Okay, this one has me baffled. I mean, the whole situation was a painful one, but it was a bunch of people yelling "racist" over a crazy man who thought a kid in a dark hoodie, going around the neighborhood late at night, was breaking into houses on his street. Paranoia kicked in and he stalked the hooded figure with a gun...got his ass kicked (don't deny it either, the police reported as such besides the images of him with bloody head wrappings), used said gun, and shot the kid. Zimmerman was Latino, not white...so that's why I'm lost on it's relation to this comic joke. The problem with the whole Zimmerman situation is that the parents of the kid (who couldn't bother fully explaining why their teenager was in that neighborhood, that late at night), as well as other figureheads ('Reverend' Jessie Jackson) were all trying to play the race card in a tragedy that seemed to be at fault of both parties without consideration of race pre-shooting.
Parts of the joke are lost in some context that I don't quite get, but the overall joke of "white heterosexual male 'lunks' are complete idiots" I did enjoy. Thank you.
