Last time I checked being white didn't mean we agreed, honky

Yesterday I went to the gym with a buddy of mine. After a while we wanted to get on the chest fly machine. So we go over there and there's an African-American fellow wiping down the machine. He told us we could have the machine when he was done wiping it down (which is good etiquette). When he finishes and walks off some white guy comes up and starts to wipe down the machine. "Oh were you working out with the other guy?" my friend asks, "'cause he cleaned the machine already."
Whitey tells us no and just states tat he thought it should be cleaned again because "guys like that leave residue."
Needless to say my buddy and I, who are both white, were shocked. Which leads me to the question, my fellow white males: why the fuck do you think you can go up to any other white guy, say something terrible, and expect them to agree? This isn't 1945. What you think isn't right. What you feel isn't right. And sharing it with others doesn't make you any more right. If you're counting on other white boys to justify your grandpa's ass backwards ideas, you're a dying breed. A lot of us are getting fed up with it. So keep it to your damn self.
