[oxymoronic]

At that time in Christian West, the notion of "Judeo-Christianity" would be considered an oxymoron. But it is possible that the general is question is in fact alluding to that era from ignorance.

Judeo-Christianity here just means Old+New testament. They just didn't use that terminology back then, but the notion was very much the same.

So "Judeo-Christianity" in this context is just a euphemism for "Christianity."

> What has become known as the People's Crusade passed through Germany and indulged in wide-ranging anti-Jewish activities, including the Rhineland massacres.

Yes, as it's more often than not used. It's basically "what evolved as Christiatity, through the adoption of Judean-originating ways of belief" (as opposed to pagan ones).

No. The Notion was not very much the same. Medieval views of the Torah / Old Testament were very much informed by anti-semitism.

Medieval crusaders would have balked at the idea that Jewish and Christian values could have any form of harmony.

You missed the whole point of the comment:

"Judeo-Christianity here just means Old+New testament. They just didn't use that terminology back then, but the notion was very much the same".

The didn't say "Old+New testament" but it meant exactly that, what scholars for a couple of centuries now refer to as "judeo-christian".
