Since we can actually measure & look at people in a very non-debatable way, you can get unquestionable & unbias data on how tall people are and the color of their skin. You cannot debate 6-foot tall versus 7-foot tall. We've(first-world at least) all agreed on what is a ruler. 12 inches is 12 inches. You also cannot debate the color red versus green as it has been defined.
The OP's generalization of people being equal is a fair generation to make considering the context of the world we live in today.
You should understand and be sensitive to the fact that racism is a real problem in the world today. As such, statements/questions implying directly, or indirectly, a characteristic of a group of people that support ideas aligning with racism should be done with care and not without quality evidence that suggests the negative characteristic; otherwise it just appears malicious. Especially for a group of people who have already experienced very similar abuse for many years and are still dealing with it today.
