The Western world as we refer to it and its influences is no longer considered modern society. Technically speaking. It’s called postmodern.
Honestly I am confused too and trying to figure it out.
From what I have gathered thus far, the paradigm shift towards an individualistic society where everyone does his or her own thing comes from the Postmodern era beginning in the 1950s.
From Revise Sociology:
“Post modernists argue that we live in a ‘Pick and mix’ society. Individuals today are free to pick their lifestyle and life course, from a wider range of options than ever before, just as if they were picking and choosing products in a super market!” (Revise Sociology)
Sounds like postmodernism is what we associate with the threat to Yiddishkeit.
