There is no doubt that Jewish intellectuals and activists have played a major role in creating the complex of ideas that has favoured the mass immigration of non-European peoples into European societies, in effect opening the gates to Mohammedanism, among other evils. But to what extent did or do ordinary Jews share these views? Here are some extracts from a book called "London Jewry and London Politics 1889 - 1986" that cast an interesting, and, to me, unexpected, light on this question.
This suggests that the pro-diversity activism of Jewish intellectuals and, to some extent, their notionally representative organisations, was not widely supported by ordinary Jews.
In turn, this raises the issue of the extent to which "Jews" can be held accountable for the actions of elite Jewish intellectuals or nominally Jewish organisations.
It's a bit like the question of whether it is right to hold ordinary Muslims accountable for the actions of violent Jihadists.
It seems to me that the right way to approach the question is from the perspective of the indigenous people contemplating the possibility of having an exogenous group living amongst them. The relevant question is: what bad things are going to happen to us if we allow this people to share our land that wouldn't happen to us if we kept or drove them out?
History tells us that if you have Muslims living amongst you, you are going to have jihad. A certain percentage, even if a small one, of Muslims will always be drawn to jihad. Even if those involved represent a minuscule share of the overall Muslim population, they can still have a significantly detrimental effect.
Similarly, history tells us that if you have (emancipated) Jews living amongst you, a certain percentage, even if a small one, will become influential intellectuals, journalists, academics, lawyers and politicans who will use their power they acquire to create, advocate and implement ideas that subtly denigrate and undermine the traditional culture, character and power configuration of your country, portraying it as somehow pathological and in need of "healing" through disruptive, even destructive, transformation. Even if those involved represent a minuscule share of the overall Jewish population, they can still have a significantly detrimental effect.
In both cases, therefore, it is reasonable for indigenous European peoples to conclude that we simply don't need the grief, we don't care whether it's a tiny minority or not: we just don't want the problems we know you are going to cause us therefore we're not going to let you in or we're going to politely ask you to leave.
