I'll say the same thing I said before. It's not a reference, but if it was, I wouldn't care. Not because I'm racist, I'm not. I just don't pretend to care about things that don't effect me and *gasp* don't really matter.
Moreover, I think that a lot of the people bringing up this issue actually ARE racist for seeing a black dude in a hoodie and screaming trayvon. They are also using a dead kid to push an agenda, which is pretty low.
Do you honestly believe that this huge conglomerate of a company would throw a reference like this into a game that they've been working on for that past several years? Do you really think that Ubisoft would take a tasteless, unprofitable gamble that could potentially lose them hundreds of millions of dollars, as well as their good-standing in the public eye? What in God's name would be their incentive?
"Well we may lose everything, the future of this company included, but this stupid little easter egg is sure gonna be funny!"
Actually, OP, don't respond to this. You clearly just haven't lived long enough or experienced the world enough to have a decent idea of what is common sense. Maybe just take a break from forums for a little while and go see the world.
