What you're saying is the exact reason why people should be treated as individuals. Because, yes, general biological and behavioral trends form in racial and ethnic groups. However, as you've said, many people do differ from the average of any given trait among a particular group. Therefore, people should always be treated as individuals and not judged due to immutable characteristics. I'm not really sure what your point is in your comments? You need to abandon the collectivist mindset and leave that shit for the leftists.
