Identitarianism is just another non-Theistically based, and therefore, groundless philosophy--just like "social justice" for the Left (as a matter of the fact, the modern Left is itself more identitarian than Marxist).
People who don't acknowledge the Master of the Universe have to invent artificial reasons to live. One is "social justice," a groundless and ultimately illogical "moral" system when divorced from G-d and His Commandments. Others instead pick ethnic/cultural identity. Some even make a fetish out of "traditionalism" without any regard from its Divine Source. There are rabid anti-Semites who accept Torah/Noachide morality because they think it is a creation of "western man" and who reject HaShem and the Bible (accept as part of the culture of some of their "racial brothers nad sisters").
It makes no difference if one is "liberal" or "conservative," "traditionalist" or "radical," so long as one believes in an impossible "independent" morality that exists apart from A-mighty G-d.
Instead of a neo-pagan ancestor worship, why don't all of us turn to our Creator?
“Instead of a neo-pagan ancestor worship, why don’t all of us turn to our Creator?”
You mean like the Zionists in Israel?
As for “creator” which one do you mean, the Jewish, Christian, Muslim, Chinese, Japanese, hindu, Eskimo, tribal African, Aztec, etc?
