I would definitely urge people--especially college students and professors--to watch this documentary. Watch and listen. Listen without formulating a response to every scene that the filmmaker creates. You may just find yourself a tad enlightened. The film-making is not great, but the information contained therein is quite good.
My experience getting a Ph.D. was precisely like what is portrayed in "Indoctrinate U." Would I have proudly announced my conservative leanings to my professors and peers? Heck no! Only unless I wanted to be a campus outcast and have no professor willing to serve on my dissertation committee. Would I have admitted to listening to Rush Limbaugh on occasion or being pro-life? Perish the thought! Only unless I wanted to spend four years receiving dirty glances and hateful comments.
Maybe everyone's experience wasn't mine, but the modern-day university isn't a place a thought-diversity . . . and in my book, that's the most important type of diversity there is.
