I knew about the prohibition against Jews owning land and engaging in certain professions and the reason they had shops, handling money and eventually engaging in international finance. And of course the reason their role in international finance became so large was because most wealth was local as most nations had rules against too much capital leaving their borders. Of course in every country in which Christianity was dominant they had periodic pogroms murdering the Jews and stealing their property (where hate for the "Jews who killed Christ" and avarice and jealousy of their wealth combined. Just like here, to watch anyone who looked like they had it better than they did produced envy and anger. The Jews in those communities had to have a way of getting at least some of their wealth out of the country if they had to suddenly flee because they would be destitute as refugees if they could not get at least some of their money out, hence the Jews often knew someone who knew someone who could secretly convert some of their money into forbidden foreign currency. (You know the old joke about why so few concert pianists were Jews - because it's hard to carry your instrument on your back when escaping.)
So there we have the beginning of conspiracy of super powerful Jews controlling all the money in the world. I have a huge question I wish those people would consider. If these "Jewish financiers" were so all powerful, why wouldn't they have halted the holocaust right after it was started? Do they really think that these powerful people would have allowed this to happen to their own people after the first camp was up and running? Millions!
Then we have the deniers that all those people were even killed. My first experience with this was in the summer of 1976 when coming out of a church service with my then husband and finding fliers on all the windshields of the cars. I was so shocked by the polemic that these fliers contained. So hateful against Jews and claiming most of the claims of the camps were lies and fabrications. Fake evidence that they existed. No gas chambers, no ovens. And of course the Jews were behind it because they wanted sympathy or some such thing. (Gee. just like an insurrection never happened here, just some demonstration.)
Anyway, my husband threw the flier away as ridiculous and would never amount to much, just some disgruntled angry people stirring up people. So, we have this happening again, spreading the hate to new groups who either haven't paid attention to the truth or reject it because they don't want to believe it or it's inconvenient for them to acknowledge it. Why do people even want to believe this? (Some people even say, "I don't want to believe this, but..." as if one fact really leads to another and makes them hate.
