Wednesday's episode of ABC sitcom Blackish treated Republican African Americans as abnormality that could not be tolerated. Father Dre Johnson, played by actor Anthony Anderson, began the show by proclaiming: "There are certain things in life that are just true. Fact: The Earth revolves around the Sun. Fact: Two times two is four. And fact: Black people aren't Republicans. We just aren't. We vote for Democrats."

He added: "Sure, the other side may trot out a token black face every now and again, but the fact of the matter is, being a black Republican is something we just don't do."

The cold open concluded with oldest son Junior, played by Marcus Scribner, revealing to his father: "I joined the Young Republicans club at school." A shocked Dre drops the glass he is holding.

In the next scene, a worried Dre tells his wife Bow: "We have a problem. Junior is a Republican." Bow Johnson, played by Tracee Ellis Ross, is so deep in denial that she misunderstands him several times until he explains: "Ronald Reagan. Ann Coulter. Fox News. Tea Party! Bow! Republican!"

Bow reacts in complete disgust: "Republican?...No!....We don't do that, Dre! We are compassionate liberals who believe in tolerance, acceptance, open-" Dre interrupts: "Yeah, yeah, yeah, whatever. But we're black, alright? That's all that matters. We're black." Bow demands: "When did he start believing that immigrants should go back across the border, that evolution doesn't exist?!"

The same bit is repeated with Dre's mother Ruby, played by Jennifer Lewis, who, after finally accepting the news, wails: "No, he can't be a Republican! [Crying] Oh, my God! Not a Republican! Oh, Jesus! Black Jesus! Sarah Palin!"

Later in the show, Dre shares the development with his co-workers, asserting: "Look, you can do anything, but you can't be a black Republican. They are not down for us, so we are not down for them." His boss Mr. Stevens, played by Peter MacKenzie, pushes back: "Are you saying all Republicans are racist?" Dre replies: "No, of course not." Then he lowers his voice and says to fellow African American Charlie: "But they are." Charlie, played by Deon Cole, warns: "Look, you just gotta do something about Junior. You don't want him to end up an Uncle Tom."

The episode does depict Dre and Bow confronting their own intolerance and prejudice toward black Republicans, but the overall tone is clear: An African American being a conservative Republican is the ultimate betrayal.

It's not the first time the show has strayed into politics. The April 22 episode featured younger daughter Diane, played by Marsai Martin, dressed up as her "hero" Sarah Palin for a school project – much to Dre's revulsion.
