Possibly belated recognition that Marx and Engels were " scientific racists " and Judaism is a religion that includes several ethnic and language groups. Hate filled bigotry is another way to shed more light than heat in this noisy debate.
The battle against quack-science racism starts here.
Capital, vol. 3, chapter 47: "The possibility is here presented for definite economic development taking place, depending, of course, upon favourable circumstances, inborn racial characteristics, etc."
Engels: (Marx and Engels, Selected Works, Vol. 3, p. 502.): "We regard economic conditions as the factor which ultimately determines historical development. But race is itself an economic factor".

Hollander and Lehren are of the Portuguese sect of Jews, and practice a great ostensible devotion to the religion of their race. . . . "
