The yahrzeit -- year's time is the direct translation -- is an anniversary of a death day OF AN INDIVIDUAL. The candle is an outward expression of it. The death OF AN INDIVIDUAL.
This Zoom crop of "Jews" does not reflect all Jews, anymore than Biden reflects all Americans. The stunt -- memorialize a Supreme Court decision -- is an utter misuse of the whole tradition. And contemptible.
But as we see across Christian denominations as well as Jewish, the schisms are ever more easily being seem. The "liberals" will turn their traditions to the service of liberal politics, while the Jewish Orthodox and Christian Orthodox and other traditionalists will not. Plain and simple, Leftist politics has infected pulpits and the media is amplifying politics by subverting religions -- plural.

Like Protestantism, Judaism is highly fragmented and to a great extent congregational. Unlike Protestants, Jews exist as an ethnicity as well as a religion. Some groups that are rooted in Protestant background, such as Mormons, Jehovah's Witnesses, and Unitarians, have ceased being Protestant. The wide spectrum of Jewish beliefs, or for that matter nonbelief, does not disqualify any of their adherents from being Jewish. Only leaving Judaism for Christianity, Islam, or some other religion is the point of separation.
