“”A lot of Americans have never visited a mosque””

Actually, they do it quite frequently in places like Pakistan and Nigeria . . . for the express purposes of gunning down and blowing up Christians.
As for the relationship of Christian and Arab, the Koran, Sura 3, verses 28-85 is perhaps the best exposition of the Muslim-Christian/Jewish relationship. Verse 85 ends: And whoso seeketh a religion other than the Surrender (to Allah) it will not be accepted from him, and he will be a loser in the Hereafter.

This is one reason why Italian journalist Oriana Fallaci was so anti-Muslim immigration: she considered resurgent Islam to be a revival of the fascism she fought against in her youth. She was not a Christian, but she loved Christian culture, which she recognized as the font of everything that's good in the European identity.
Myself? "If they want to live by Sharia, I don't want them to live by me."
