Comedian Bill Maher faced some backlash on Tuesday after he expressed his disgust with radical Islamic groups following reports that Islamic State militants beheaded an American journalist on video.

Maher appears to have been making the point that there is a disproportionate level of violence in Islam compared to other religions, though he never said that all Muslims are terrorists or violent. Some Twitter users were apparently outraged by his comments.

“F*** you in your ass Maher,” one user replied. “What do you know about Islam? Where does it say in the Quran to behead ppl?”

“Yeah like Israel killing people in Gaza is any different. Good call Bill good call,” another person wrote.

A different Twitter user said Maher sounded like a “right wing f***tard.”

However, Maher also saw plenty of support from people who agree radical Islam poses a serious threat to the rest of the world.
