Rabbi Meir Kahane z"l accurately described this lack of mojo in his famous essay, "What Makes Bernie Run?" I've quoted the essay before, and I will quote it again, for it is still relevant today:
And who else made Bernie run away from Judaism? Who else made Bernie what he is and is not? The massive, gaudy mausoleums that dot the landscape of every Jewish suburb. The temples. The temples whose senior rabbi is the caterer. The temples that perform human sacrifice rites each Sabbath morning and they call them, The Bar Mitzvah.Rabbi Kahane's description of the "Temple", written way back in 1975, was painfully accurate. There was absolutely no mojo there in those Temples, so it is a waste of time to look for it.
The Bar Mitzvah, that is not the beginning of a Jew but his end, his spiritual death. The Bar Mitzvah- that culmination of an empty, vapid, childish, shallow Jewish "education," taught by men and women whose ignorance and lack of Jewish content makes them superb vehicles for the "education" they pass on. The Bar Mitzvah, that obscene cult of ostentatiousness, the ultimate in Jewish status seeking, the competitive drive to bankrupt that pathetic and hapless "father of the Bar Mitzvah." The Bar Mitzvah where the young lamb babbles the words he neither understands nor cares to, to the accompanying nachas, pride, of beaming women and men who would not know a correct word from a mistake, whose ignorance is sublime and whose disgusting display of conspicuous vulgarity sends G-d fleeing from the mausoleum in wrath...
The Bar Mitzvah whose necessary "religious" interlude long ago was subordinated to the piece-de-resistance of the entire immorality play - the "reception." The sickening waste of money and degrading of Judaism, where materialism runs amok in the guise of religion, where drunks and half-dressed women dance and give praise to the L-rd, with African dance, American tunes, and universal abomination. The Bar Mitzvah where the assimilationists, ignoramuses and despoilers of Judaism, beam with patronizing pleasure as the decrepit grandmother- Bubby- is resurrected from her nursing home or Miami Beach condominium and trotted out to light a candle to the applause of the go-go girls and dirty comedians waiting to do their act.
The temple, where man thinks up G-d rather than admit that He made him. The temples, where the Jew can create any kind of religion that he cares to and call it Judaism. The temple, where things too difficult are junked and where from the Board of Directors shall come forth Torah and the voice of the L-rd from the approving Sisterhood membership. The temple, run by men whose ignorance of Judaism is exceeded only by their arrogant insistence on saluting it. The temple, where Bernie visits "G-d" and meets "Judaism" and flees from it in horror. The temples: they created Bernie, they made Bernie run.
