In recent years, Amy Schumer has emerged as one of comedy’s biggest stars, a performer and writer who has used her visibility and Emmy Award-winning sketch series, “Inside Amy Schumer,” to call attention to a wide range of social issues that were once considered too uncomfortable to joke about, be they the chauvinistic depiction and discussion of women’s bodies in the media or the public’s unwillingness to believe sexual assault charges made against Bill Cosby.

But now Ms. Schumer finds herself criticized because of her association with a colleague and fellow comedian, Kurt Metzger, who has written for and appeared on “Inside Amy Schumer.”

On Sunday, Mr. Metzger published a post on his Facebook page that appeared to be in support of another performer who said he had been barred from the Upright Citizens Brigade Theater following allegations that he had raped or sexually assaulted women.

Mr. Metzger, who did not give this performer’s name, wrote sarcastically in his Facebook post that he had “just heard some disturbing news,” implying that it was true because “because women said it and that’s all I need!”
