In Which a House Republican Accuses John McCain of Making a Racist Joke

Today, a Twitter drama in four acts. Act one: Screen shot 2013-02-04 at 12.00.50 PM In Act Two, we are introduced to Rep. Justin Amash, son of a Palestinian immigrant, thorn in many Republicans’ sides.
Screen shot 2013-02-04 at 12.03.39 PM In Act Three, McCain brushes aside the critics. Screen shot 2013-02-04 at 12.02.01 PM
And in Act Four, Amash says the cruelest thing that you can say to any white person. Screen shot 2013-02-04 at 12.04.07 PM I’m no expert, but I believe the “racism” accusation is based on Ahmadinejad’s swarthiness. Did McCain ever end up backing down on his early 2000s usage of the word “gooks”? Did Gran Torino retroactively make that ironic?
