The again, had the Catholic Church NOT prevented Jews from joining guilds, i.e. learning a respectable trade etc., attend university, fight in the army alongside their gentile neighbors, that is, die as well as live with them,
Well, they were from Africa in the first place and were expected to integrate in a generation or two. Why special treatment should be a norm? That the vibes I'm getting from many Jews - expectation of special treatment?
If you move to another country you either integrate and respect your host's way of doing things (especially in few generations)or move out if you don't like it.
Instead of gratitude for lax treatment in Europe (for the most part?),which allowed them to survive they wallow in vindictiveness and ungratefulness.
