Absolutely bone chilling. It is this kind of "rumors" that carry unacceptable probabilities of leading to real pogroms.
Anyone caught amplifyjng them should be shunned until they show remorse of their actions. Anyone caught initiating them should be banished from any platform until they make amends.
Of course that happens only in a society that still has the power to clean up it's own information sphere, and is not stuck in some loop of doom and terminal information pollution.
