That game was amazing, I'm 2 for 2, but got the letters wrong on both.
I think there is a little cultural confusion with people thinking reda is racist. You see, although America is stereotypically known as a place where we think we are exceptional and the greatest place on Earth, not everybody is like that. Those who aren't really like that will often joke about those who are not with sarcistic jingoist chants and cries. Typically, if somebody actually believes those sorts of things, they will not refer to the U.S. as "Murrrica!" intentionally as Reda did. I think he's just kind of going over the top and joking about the whole U.S. vs. THEM theme this year. Whether it is actually a funny joke is up for debate, however, he's not really acting like an American chauvinist in a sincere way.
