Hey, generalizations are sometimes legitimate. And sometimes they are absolutely valuable. For example, a totally racist but accurate statement is that the majority of people living in subsaharan Africa over the age of, say, five cannot drink cow’s milk. (More accurately, they cannot effectively obtain nourishment from it, and it causes digestive upsets to some.) This is clearly defining a racial stereotype, but it is also valuable information for, e.g., someone exporting non-fat dry milk, whether commercially or for a charitable organization. My point is that race is not something to be ignored, just treated as a characteristic.
I know thoughtful and compassionate atheists (some on this board) and thoughtful and compassionate fundamentalist Christians. And I know bigots in both categories. I do not plan on inviting Satan to any church rallies, but if we get into a social justice outreach program, I intend to get in touch with him right away. Why? Because I respect where his head is, on both subjects.
One must deal with the individual and respect his or her dignity. But because there are so many individuals, and because we as human beings cannot learn and index sufficient information about so many individuals, some useful generalizations will help. They only become evil when we mistake their generality/summary/typicality nature for an absolute about all such people.
The best classical clarinetist I’ve ever known was an elderly dairy farmer who looked like how Barney Fife would appear at age 80. His son, who closely resembled Leif Garrett wearing a black wig, turned into an extremely competent meteorologist. A coworker who runs the mailroom/copy center is a trained and competent chemist who just happens to like what she’s doing enough to stay here. The best proofreader of my acquaintance also plays tabla drums professionally and is a competent steelworker with several years construction experience. (FTR, the latter two happen to be black.)
