The host of a radio show that has become a regular stop for Republican presidential candidates is calling for restrictions on Muslim immigration to the U.S.

Bryan Fischer, who is the American Family Association’s Director of Issues Analysis, also called Islam a “toxic cancer” on his show today. This is not new rhetoric for Fischer, but what makes it interesting is that several potential GOP candidates have recently accepted invitiations to be on his show. That includes Tim Pawlenty, Michele Bachmann, Haley Barbour, and Newt Gingrich.

“We really need to restrict immigration from Islamic countries,” Fischer said today.

Here, via Right Wing Watch, are his latest comments:

We allow unrestricted Muslim immigration into the United States, we are welcoming to our shores, welcoming to our borders, men who are determined to destroy us. They’ve said it themselves, it’s in their own writings, it’s in their own words; they’re out to eliminate and destroy western civilization. It’s just absolute folly to invite that kind of toxic cancer into our culture, but that’s what we’re doing every single day.
