1) White privilege is the premise that people with white skin are more privileged for being white.
2) No one believes that all white people think the same, which incidentally rolls back to the premise of white privilege. Many black people know what it's like for people to judge their entire race based on the mistakes of a few (and it will more often be mistakes). Skip work and it's not "Mike is lazy," it's "black people are lazy." Take money and it's not "Tyler is a thief," it's "black people are criminals." It constantly happens, and many of us are cognizant of that in our daily lives.
White people, on the other hand are judged as individuals. A Tumblr bingo card doesn't approach the level of trying to change that, and that won't change. Obviously there are individuals that will judge all white people for the actions of the few, but the fact of the matter is white people hold the advantage here, by far. We've already seen the media conflate the rioters with peaceful protesters as we've read this thread. White people will (most likely) never be judged in this manner. It's non-issue, and I can't see how you guys believe that you're being lumped in just because you're white. By and large, you never have been, and today really isn't any different.
3) This is a huge tangent.
