nobody is saying that all Hispanics are bad.
I know, but sometimes it sounds like people mean to say "all", they might misunderstand it I guess.
Nobody is saying "all" but then people can say "most" are "bad" instead.
A CONSERVATIVE TAKE ON GENERALISING:
It should be taken for granted that a statement beginning with.."Blacks are......" or "Arabs are......" or "Mexicans are......" is going to refer to the majority of them in general terms and not every, single one on the Planet.
Saying "group x are..........." is NOT saying "every single member of group x are...."
For example:.
When we say that blacks* are a criminal society, we don't need to show that 100% of blacks are criminals, we just need to show that there is a severe criminal problem that is more pronounced among blacks than anyone else. If that is10% of the population, 30% of the population, 40% of the population, so be it, the exact numbers are inconsequential it's a question of per capita or proportionality.
*The same applies to mexicans & arabs being dirty, lazy and envious.
When we point out anti-Semitism among Polish people for example, we don't need to prove that every single Polish person is an anti-Semite, we just need to point to the uniqueness of the problem to Poland, the pervasiveness of the problem, and the degree of the problem.
When we say Toyotas are reliable we don't mean every single one of the millions produced is. There are a few examoles of badly built or designed Toyotas but GENERALLY speaking the evidence of thousands of owner surveys and quality reports suggests that Toyotas ARE reliable.
These are the modes that these sort of things are discussed in and indeed when speaking of general habits of cultures and religions, this sort of thinking is commonly used all the time. Why should it not be used in reference to blacks, muSSlims, mexicans or anybody else?
