I was trying not to get into this false equivalency, but...
You cannot satirize all faiths as if they're -- at this moment and in this country -- equal. The LDS church is a wholly American-originating church. It's young, it has a lot of followers around the world and has had a lot of issues with the white savior complex, colonization, racism in its past (the 1978 joke), a presidential candidate, and a bunch of Osmonds. Islam is much older, much more issue-laden, doesn't have a lot of visible entertainment-oriented followers, and currently its American adherents are undergoing a lot more hate crimes than any Mormons out there.
I love the show and I realize it has a few "punch-down, not up" issues, but in this case, they are punching up. That wouldn't be the case if they'd chosen Islam. Which they did not. Hence the irrelevancy of this really stupid comparison.
