Have you ever thought you might just look lost and people are trying to help out? Why do you immediately think everyone is somehow racist by asking you this question?
"Too often, however, this means that by week six in the ten week quarter system, the class enrollment makeup drops dramatically from being optimistically diverse to being exclusively male, white and Asian."
It's because the classes are difficult. I took these classes when I went to school and if you don't really know your stuff, you will fail.
I don't know the person that wrote the article, but it seems she wants to be taken seriously immediately. Nobody gets taken seriously immediately, even if you are white or asian. Everyone has to put the work in.
"I can put that power to good use by creating more spaces for minorities in technology to thrive and feel welcome"
Why don't you just say African-american students. Asians and Hispanics are also minorities.
When I went to school, I had many African-american students that were my classmates. As the classes went from 100 level to 300 level and above (major-level and weeder classes), many dropped out.
They were never treated any differently in class. We also need to remember that many universities have quotas for minorities and give extra points on the SAT for just checking a box.
This however, does not guarantee that a person has the knowledge to actually pass the classes once they get in.
