Clarifications
1. The title is over the top, designed to inflame. Just as liberal stereotypes of conservatives, CEO's, oil companies and others are not always accurate (but used regularly). I am sure there are liberals genuinely interested in a color-blind society and who conduct themselves in a way that promotes that goal. That being said, liberalism in this country is in general very reactionary against anything outside its basic coda, and affirmative action and systematic oppression of minorities by whites or especially white men is a regular topic among most liberals. That they are engaging in the same bigotry they condemn is lost on them. When you are morally superior, bigotry is somebody else's problem.
2. Mike Adams is not a professor at Univ. of Delaware, which is the subject of the article. The FIRE organization is the one who kicked over the anthill and if you desire to be more informed, I suggest you follow the link in the article to their website.
3. This problem is not limited to Delaware, as the Ward Churchill saga, the shout-down of David Horowitz at Emory and takeover of the stage at Columbia when the Minutemen founder tried to speak there show. In cases related to freedom of speech, many liberals see it as a one-way street. Their views about who might be racist and what should be done about it are similarly ideological and uniform.
4. Hillary Clinton learned a great deal from Saul Alinsky ideologically. Her first job out of college was "working with the underprivileged" as an assistant to the head of the CA Communist Party, whom she became acquainted with through her legal work in college to aid the Black Panthers. She bills herself as an "old-fashioned American progressive", whose conceptual inspiration and framework, if not exact quotes, flow from Karl Marx. There are a series of quotes from the woman herself that with slight word changes spring right out of marxist "thought". If you don't believe it, then IMO you are blinded by your own ideology or you are uninformed, by intent or negligence.
