Rock head sounds like he was man-splaining or whatever that goofball video meant. If you are white, don't ever say that one has Black/Hispanic/Asian friends.
To even attempt to crawl into their thought processes is exhausting.
MM didn't look at the source, kpete, and realize the meme was a

-parable intended to bolster DU-folks' faith in the
Russia-Hacked-The-Election narrative.
As for MM's
right-back-at-ya- 
, I'm sure there were prejudiced teachers back in the 1960s. I don't remember any, but he grew up in a different part of CA than I did. Here's my
counter- 
. The schools I attended in and around a medium-sized Central Valley town in the 1960s and early 1970s were "integrated". Those same schools were "integrated" as early as the late 1910s when my parents entered school; frankly, I doubt that county ever had racially segregated schools. Knowing how what Progs call their thinking works, yes, my classmates included children of black, Hispanic, Chinese, Japanese, Indian, Native American, and Korean ancestry. That I can recall off the top of my head. And they were involved in things like student government and leadership in band and cheer leading (things where both ability and popularity mattered).
It's funny how the reality I experienced differs from what MM claims to have experienced. It's almost as if
generalizations generally don't work when humans are the subject.
