Marxists first and Jews only incidentally.
Check this oppositional group of Jews and similar oppositional groups, for ties to NGOs. Several years ago, I was shocked to hear about a Jewish “charity” that was making big money helping illegal aliens learn how to tackle and conquer our welfare system. I now understand it was most likely an NGO exploiting the system as a means of making a living. I think the group was located in western Massachusetts. I don’t recall the organization name, only it appeared to be a profitable non-profit.
