By that token is it also sexist because he said "dude"? Where do you draw the line? Seriously, not every mention of race is racist. Saying this is racism cheapens the whole idea of racism and hurts whatever it is you believe you're fighting for by "calling it out". You're effectively putting a guy who mentioned someone's (hypothetical, as it's not even in reference to a real person) skin color in the same category as people who burn crosses, or deny people of color job opportunities based solely on race, or lynch children. To put it in terms appropriate for HN you're adding an extremely small outlier to the data set of "racists" and thus bringing down the entire average.
