FRESNO, Calif. — As the drama over offensive comments by two television stars gripped the nation last week, much of the attention focused on President Trump’s Twitter responses: his decision not to condemn the racism in Roseanne Barr’s tweet, and his questioning of whether there was a double standard at play.

Why, he asked, did Ms. Barr’s remarks result in her show being canceled while ABC, which aired Ms. Barr’s show, had never apologized to him for the network’s many perceived offenses against him?

The day after Ms. Barr’s tweet, Samantha Bee’s vulgar reference to Mr. Trump’s daughter Ivanka amplified the argument. Why wasn’t Ms. Bee losing her show, the president asked, suggesting an inconsistency under which the conservative Ms. Barr was punished harshly while Ms. Bee, a Trump-bashing liberal, received a pass.

That sentiment resonated here in the Central Valley communities of California, where Christian conservative values run deep. Evangelicals have long complained that they are lampooned based on caricatures of their faith, resulting in little or no outrage.
