Tina Fey found herself in uncharted waters this week.

Fey, a liberal who tweaked both sides of the aisle on NBC’s “30 Rock,” got busted by the PC police. Her crime? An episode of her show “Unbreakable Kimmy Schmidt” was deemed “racist” after Netflix unveiled “Schmidt’s” first season earlier this year.

The “Sisters” star likely earned some protection due to her politics. Her Sarah Palin impression alone may have bought her additional time. Eventually, someone asked her about a running gag on the series.

Jacqueline Voorhees (Jane Krakowski) appears white but is part Lakota Indian. She previously denied her ethnicity. She later accepted it when it worked on her behalf.

Did Fey back down? Apologize? Grovel? No. She simply refused to accept the premise of the attack.

“My new goal is not to explain jokes,” Fey told Net-a-Porter according to TheWrap.com. She blasted the “culture of demanding apologies” during the Q&A.

“I feel like we put so much effort into writing and crafting everything, [The jokes] need to speak for themselves,” she added.

“Schmidt” co-creator Robert Carlock addressed the storyline earlier this year before the Internet storm erupted.

“We have a couple of writers on staff with Native American heritage … So we felt like we had a little room to go in that direction,” Carlock said.

Fey isn’t the only liberal comic under assault by the PC police. Amy Schumer recently got pummeled by the same mindset.

A Twitter user wanted the “Trainwreck” star to reveal her “responsibility/value system as a storyteller,” according to The Hollywood Reporter. The Washington Post also piled on, calling her routine racist.

One of the jokes in question? “I used to date Hispanic guys, but now I prefer consensual.”

“I am evolving as an artist,” she added. “I am taking responsibility and hope I haven’t hurt anyone. I apologize [if] I did,” Schumer responded.

It’s why the new documentary “Can We Take a Joke” matters. The film asks button-pushing comics like Adam Carolla, Lisa Lampanelli, Penn Jillette and Gilbert Gottfried how their careers are under attack from PC sensibilities.

Carolla has long since embraced Fey’s model of defiance. He doesn’t apologize for his jokes, period. He has an advantage over Fey. He operates his own “pirate ship,” an independent podcasting network where he calls the shots.

Fey, in comparison, typically works within the system. So even if she stands tall against PC attacks her bosses, be it Netflix or any film studio, could convince her to apologize.
