I've actually looked into it and it doesn't seem that anyone really knows what the term "Jew" is supposed to mean, maybe you do. It doesn't really denote a religious affiliation, an ethnicity or apparently a common goal. The only thing really attached to it is a kind of Katamari Damacy-like history of picking up people who apparently like calling themselves names. That's fine, it's your term, you have fun with it.
As I'm sure you've noticed, there is quite a bit of disapproval against "the Jews", even more than usual. This is just an awakening populace trying to find out who stole everything, including that nailed down and the nails, while they were sleeping. You know, cleaned out and collapsing monetary system and expanding world war, and all that. I'm sure you'll excuse the case of mistaken identity having been applied by the groggy general population, which is understandable since a lot of the thieving bastards responsible have taken to calling themselves "Jews" and your country is apparently run by a bunch of murdering fuckheads, though that last part is hardly unique as far as countries these days go.
So be vigilant for an infestation that has been going around. Labels, as we've established, are inadequate to identify the problem that is plaguing our Earth neighbourhood, so it's better to identify them by their actions, which in broad strokes are these: Starting wars and then blaming someone else, selling the weapons of war, loaning the money to buy the weapons, printing the money to loan to buy the weapons, and loaning the printed money to the government to loan to buy the weapons (???).
If you see anyone behaving in this fashion, don't give them any attention because that's really all they're after.
