Firstly, I am a different person adding to the discussion.
Secondly, you do have the ability to look into things beyond what you are directly given by others. you have the entire internet at your disposal. That criticism page was one click away from the original article, hardly "spelunking" if you were legitimately interested in criticism of the field. I figured I would help you out with a little more information, and you downvote. So something tells me you aren't actually interested in learning anything here, just burying comments you don't like.
Lastly, as i said, you need to do some reading between the lines. Obviously no one is going to present their field in an overtly racist manner. All the criticism above leads to politiziation in the field, including racism. When you are not bound by empirical science, personal biases fill the void.
