Anything that says 'all jews' are this or that are presumptive at best and most often wrong. The personal psychological variations within groups are greater than the averaged psych variations between groups.

If someone just says 'jews' are this or that, they are generalizing which can be useful in an approximate way. Such imprecise speech risks false messaging and may done out of carelessness, ignorance or malice.

Simplifying the problems of the world with simplified views such as: America's all great, Jews are all bad, Catholics are all pagans, Africans are all whatever, etc. could be a reasonable place for some with limited info to start, but it doesn't take much research or logic to see that "all" (expressed or implied) should be "some", "many" or "most". Deeper analysis would include a proportion or percentage.

It's the ideology and activity of people that make them harmful not their genetics. Group association is often a factor in a person's relationship with the world, but it is not the only factor. Knowing one or two of a person's associations is never enough to assess them as an individual. Doing so akin to intersectional sjw identity politics.

I might sometimes say "(all) people in Florida are crazy". Any quality discussion that followed, even if for humor or drama, should allow that such a claim is absurd or at least holds more truth with further refinement or nuance.

Anyone here who thinks all Jews are essentially the same is wrong but not necessarily condemned. (Defending your position with belated special definitions is just cheap imprecise use of language).

Anyone here who says "all Jews" this or that, because you think it's your duty to divide so your master can conquer, are self-condemning.
