The hosts of “The Five” discussed ISIS’ war on Christianity as Christians flee the city of Mosul.

Terrorists have offered an ultimatum: convert to Islam, pay a tax or face death. ISIS has also burned down an 1,800-year-old church and is vowing to continue its offensive all the way to Baghdad.

“They’re getting their way,” Andrea Tantaros said of ISIS, explaining that terrorists are likely getting the impression that the U.S. is in retreat.

“It seems to me that the bad guys used to look over their shoulder and assume that there was somebody there, but now it’s an empty playground. There are no teachers, there are no parents, you can do whatever you want,” Greg Gutfeld said.

He said the U.S. and Europe go out of their way to be tolerant of the intolerant.

“If you besmirch Islam in any way, shape or form, you’re going to apologize. Meanwhile, radical Islam, they will behead you if you do not convert," he said.
