Jews were repudiated as internal to Christendom while Muslims were repudiated from outside

Evidence

Here, then, is the crucial distinction between the depiction of Jews and Muslims in medieval literature, which otherwise correspond in many respects: the Muslim community is located outside, on the outer borders of the Christian community, and therefore is repudiated, as it were, at a distance; the Jewish community, by contrast, is located both outside and inside, within the Christian community itself, and must therefore be repudiated by being abjected from within. — Ivan Davidson Kalmar, Derek Penslar, Orientalism and the Jews, 228 (#corroborates, via linked claim)

Throughout the Middle Ages, Muslims were often described as “tainted with Judaism.” Christian theologians argued that both Jewish and Muslim religious practices were flawed and heretical, and furthermore, that they were collaborators, either in conspiring to undo the Church or—and this is where the monsters often appear—mutilating and killing Christian men, women, and children. Renaissance paintings of the crucifixion, the martyrdom of saints, and other scenes often feature Jewish and Muslim (typically, Turkish) figures participating in these crimes. — Sophia Rose Arjana, Muslims in the Western Imagination, 163 (#complicates, via linked claim)
