It could also mean anything from "killing Muslims is fine" to "pursuing a millenialist apocalypse", because "Judeo-Christian" is a political idea more than a moral/ethical or religious one. It contains the idea that Christians and Jews (generally meaning the modern categories) are allies (particularly excluding Islam which contains the same religious origins), but even in that move when people describe something as Judeo-Christian they almost always mean something that is "Christian" or Western European. It is based on an assumption of Christian supremacy where Christianity is assumed to be the successor religion and culture of Judaism. It almost certainly ignores any belief, custom, or practice in Judaism that does not pre-date Christianity.
