This is an appropriate argument basically any time somebody claims that [insert group here] [insert behavior of an individual here]. Groups of people do not behave uniformly; when they behave in statistically significant ways, it is not for uniform reasons.

It's difficult to reason abstractly about groups as they actually are, so we abstract that group into a uniform body - that way we can make abstract claims about their behavior without the benefit of an education in applied statistics and research methodology. It's a useful tool for intuiting behavior, but try to avoid making non-statistical claims about the members of a group of people; you will almost never be correct.
