I'd be really angry if I had any idea who these guys are.
As it is...meh.
This IS a Big Deal -- even if you're not into this College Basketball tournament (I'm not either.)
The media who heard this immediately circled the wagon and attributed the comment to "young and stupid" -- NOT "racism.") A simple apology of a "misunderstanding" was penance enough.
However, given the social ramifications and hypocrisy are an issue that's quite topical, recently there was a converse reaction of an Oklahoma Frat's "racist" song sung by drunken white boys. In their case, there was immediate and subsequent outrage and front-page media shaming/lynching for "racism." Public ostracizing and groveling for forgiveness was demanded. And even afterward, the ouster of the white boys from college, as well as disbanding the fraternity was executed as punitive measures.
