You are right, he was no scientist. But even if a "racist quack" does a good
experiment and reports it correctly, he is still right. Similarly one can
make some valid observations but create a hypothesis for them based on false
assumptions.

The white does man often looks a bit of a mess, it's been spotted by quite a
few other so called "races".
