> It is almost exclusively used when comparing to Islam. Is it? Search through 20th-century usages of the word as reflected in e.g. Google Books, and you’ll see that the term was widely used among authors for whom Islam was not even really on their radar. It wasn’t until the 1980s at least that Islam gradually entered the consciousness of most Westeners to the point where the term "Judeo-Christian" could take on any meaning of opposition to Islam.
