Hi disciple :
I actually USE the term "Judeo-Christian" a lot, but in specific contexts and mainly related to specific texts and specific beliefs.
For example:
The Old Testament is a Jewish text AND a Christian text. It is thus, a "Judeo-Christian" Text. Both religions use the text in their theology.
The New Testament is a Christian text since the Jews do not use it as a source for their theology (though they refer to it in reference to historical discussions). However, the New Testament USES Jewish texts as much of its sourcing. It is thus, a "syncretic text". It has textual ties to both religions.
Many other early sacred texts are syncretic. For example :
The Enochian Literature (e.g. 1 Enoch) starts out as a strictly "Jewish" text originating in the strict b.c. time period. It was very very popular. The Christian apostles (who were Jewish) quoted from it. The writer of New Testament Jude obviously used it as scripture and names it specifically as a source of doctrine. It is among the most popular Dead Sea Scroll texts outside of the Pentateuch and Psalms (it was the only other book found in double digit numbers in the dead sea scroll library). Later, the Christians adopted Enoch for heir usage and added text to it. So, it WAS Jewish specifically before Jesus' time. The Christians adopted it for their usage and changed it and added to it as well. Thus is became "Christian". It qualifies as a Judeo-Christian text.
Also, some doctrines ARE, similarly, shared by both religions.
The Jews believe in the 10 commandments. They are "Jewish".
The Christians also believed in the 10 commandements. They are "Christian".
They are a shared set of beliefs and are thus, "Judeo-Christian."
The usage of such terms are, I think, a bit disorienting and have unintended meaning to them that they do not have for the historian who is simply referring to certain religious mixing of texts and doctrines rather than as a term meant to dishonor or simply be a lazy term for a "abrahamic religion".
If someone says they are a member of the Baptist Church, or the Church of Jesus Christ of Latter Day Saints (mormons); or Methodist, or Jehovahs Witness, I would personally refer to them as "Christians" who believe in some Judeo-Christian texts (Old Testament) and who have some "judeo-Christian beliefs (i.e. 10 commandments). It has no derogatory meaning for me.
