Yes, but Orthodox Jews are a minority of a minority rather than an ethnicity per se. As an ethnicity, Jews marry out far, far more than muslims. Or, as in Monty's case, they simply impregnate decent Christian women with their foul Hebrew seed and then refuse to marry them.
But more seriously, it is assimilation, but crucially, it's not assimilation of the minority by the majority. And, whichever way you look at it, it sure as hell ain't integration.
