"Judeo-Christian civilization" : apart from a homily where John Chrysostom said (paraphrasing) either Judaism is true or Christianity not both, admitted for 100s of years, you'll notice that virtually all intellectuals who "made" European civilization were more or less anti Semites at the beginning of the last century this expression was in fact used, in academia, for the early Jewish converts to Christianity or "Judaizing" Christian sects (like the Ebionites).
The submission of the West to the Jews is probably the best indication of its decay but then the last "defenders of the West" are often homosexuals (Pim Fortyun in the Netherlands, Douglas Murray/Milo from the UK, etc) and the values mobilized are from liberalism (democratism, feminism, …) it makes sense : if you submit to the Jews you can *only* have homosexuals trying to "save the West" with liberalism.
Otto Weininger, himself an ethnic Jew who would commit suicide, made the connection between Jews/"femininity" (so homo./lib.) more than a century ago.
