So the problem with categorizing people into races is that there are many axes along which people can be divided into buckets, and any particular race grouping only has meaning in a particular place and time and will have totally arbitrary boundaries, which are as much cultural as they are genetic and physical. As long as people understand that, it's okay to talk about races tending to have certain qualities. Because culturally we've divided people based on those qualities.

But it's really important to understand that people of different races aren't different kinds of people. Any more than people who have blonde or brunette hair are different kinds of people.
