What's your point?
Do gentile criminals cause anti-gentilism?
Do black criminals (if they were the exception and not the rule) cause racism against blacks?
Do high-profile Christian criminals cause anti-Christianism?
I didn't read the article for lack of patience currently, but what happened in this case and I'm sure is being said is that evil criminals like Madoff invigorate the already hateful angry people out there and give them further motivation to hate Jews. He is not saying that it is a justification for antisemitism, or that it's warranted or fair or correct, nor is he saying that without Madoff committing those despicable crimes, those hateful ignorant people wouldn't still exist anyway. (If he is saying those things, he's nuts). They would still exist but this gives "fuel" for their "fires" so to speak and to rally other people to their cause. That's logical.
Are you intending to use this article to justify antisemitism? Do you think that a handful of evil criminals within the Jewish people means that we are all criminals and therefore it is ok to hate Jews? Do you claim that there are NOT a handful (or more!) of equally evil criminals in every other ethnic and religious group in the world too?
Let's hear what you have to say.
