Everything is a Generalization
Generalizations are innocent. “Dogs have four legs” is only a generalization—after all, there are some amputee dogs. And so what? But when generalizations begin “women…” or “Asians…” then people will say “oh, that’s such a generalization” like it’s some kind of criticism. But nobody could possesses knowledge only of particulars. When people complain about generalizations (or stereotypes or whatever), they are simply announcing their unwillingness to learn about the subject at hand.
Again, When you say “it’s wrong to hit women,” people don’t say, “what if she habitually inflicts emotional abuse on her child and that’s the only way her husband can get her to stop?” But if you say “divorce is wrong, people say, “what if a woman’s husband beats her and is going to kill her?” Which generalizations a person fusses over tells you something about their values.
As a rule, there are always exceptions.
