Racism is actually significantly more complicated than "people saying mean things" based on race. If there were "anti-white" bias in society then why is there significant difference in the favor of white people across basically every health and economic outcome we can measure?

The inflammatory rhetoric of a handful of people (professors or otherwise) is in no way equivalent or comparable to the historic and systemic racism faced by black people (or the discrimination faced by other minority groups). The conflation of these demonstrates a lack of understanding of what is even _meant_ by "racism".
