I just explain it like this. Every culture around the earth has crime families and organized crime.
The Italians are famous for their mafia families. The Russians they have mafia families too. The Japanese have the Yakuza. The Chinese have the Triads. In South and Central America they have the cartels. The Spanish have the Galician clans. There are Romanian mafia families too. There are even Indian mafias!
It's actually pretty foolish to think that the Jews are so pure and clean and unshakably virtuous that they don't have any mafia families within the community at large when they are just as human as everyone else. Of course not every Jew or Jewish family is part of the organized crime racket. Just like not every Mexican or Colombian is a cartel member. But it's not unreasonable to have a discussion about the alleged Jewish crime families that do exist, such as the Soros family.
It's not anti-Semitic to ask questions about whether or not is George Soros is a threat. The literal nation of Israel declared George Soros a threat, unless everyone forgot. Link below:
So, considering that, why shouldn't we be able to have a discussion about it?
Any normie that is still even halfway sane will be pretty much disarmed by that point.
Has any other group created a defense organization that goes into action the second there is any negative comment?
The ADL was created for just such a mission.
JIDF?
Anti-semitism is a shield and bludgeon to use against all that offer the slighest criticism against them, or make fun of them in any lighthearted manner. The line "if you want to find out who runs everything, find out who you can't make fun of/criticize is not a meme/joke. It's the sad truth.
I've never heard of anything for Christianity, and there might be something for islam. There's no separate organizations for mormons, scientology, because they get right out there and browbeat you so bad you slink off into a hole.
