Well not really. The biggest being Communism. Now, you can either say to yourself 'yes this is because Jews are evil' which may or may not be true in any particular instance, or you might say to yourself, 'yes, this is because Jews were close to early sources of leftist infections,' which may or may not be true in any particular instance.

Which of those explanations an individual thinks is a better fit the general picture is not very clear. It's hard to be objective about such bomb-throwing ideas and it's unlikely to find someone willing to consider both arguments, mainly because moderates knee-jerk away from fascism (which is fair, considering it's historical ties with socialism and command economies) and leftists refuse to consider the results of their ideologies even when shown the direct, well-executed causal link (#neverbeentriedbefore #notrealcommunism, etc).

Most societal problems actually require a large amount of distributed brainpower, and the way I see it, there simply aren't enough people working on this 'problem', at least not from both sides simultaneously. For instance, I personally, have no results to show for all the digging I've had the stomach for. So I'm probably not the right person for a good answer, but I can perhaps point out why I haven't seen it presented yet.
