I blame jewish culture for a lot of problems. I can't give a clear and rigid definition for it, nor could I for any other culture. I have yet to git that gud. If I were to try defining it, I'd have to go over stereotypes and their values, which I don't think most people would receive that kind of argument well. I feel comfortable using it because I don't use it like a magic wand to explain problems, as OP seems to be indulging in.

But, yeah, it is kinda like the feminism thing. They've used the cultural angle as well, even if I don't think it holds water. People like using labels and putting everything in boxes. The bigger the box, the less useful it is for organizing (like blaming a gender) - yet a small box isn't necessarily useful unless you want to exhaust yourself playing hardcore individualist mode.

Labels like jew are also difficult because it's hard to tell if it's meant as race or religion or culture. Rather, it's hard to tell if the label is meant for people that chose to take the label (by adhering to a dogma or behaving by a certain set of standards), or people that had no choice in receiving the label (by being born).
