Wrong. A generalization can be correct in certain contexts. Take the below sentence:

In general, in the United States, women tend to prefer men who are fit.

The scientific papers I provided establish the generalization within that context.

When someone makes a general statement like saying men tend to be taller than women, that someone does so with the awareness that exceptions and alternative contexts exist because such exceptions and contexts are obvious. Obviously some women are really tall and obviously the context isn't some preselected population of women who are over 6 foot.

Another way to look at my point is that broad generalizations must originate from somewhere. They are often indicative of a population where the majority or major component posseses several or a single identical trait. It is absolutely insane to ignore generalities just as it is insane to declare them as absolute truths. That is my point.

That is the unfortunate reality of the world. Generalities, like stereotypes, illustrate an aspect of a truth. Social justice is important but one cannot change the world by eliminating a truth to mold the universe into a delusion that fits the perception of a social justice ideal.
