"What is truth?" asked the powerful Roman governor of Judea, of a man accused of blasphemy two millennia ago, and we still don't know. What is "neutrality" for a university? Is creationism "neutral"? It was a huge political deal in the US for decades (though it seems to have died down recently), but in the 1980's, 1990's, and into the 2000's there were plenty of people who wanted creationism taught in science classes, or at least to "teach the controversy." Was picking sides on that topic in science class "neutral"?
Is the superiority of phonics based literacy approaches "neutral" or criticism of teachers unions? If a economics professors research indicates that, say, supply-side economics doesn't work under current circumstances, is it "neutral" for her to tell her class that? If a law professor thinks that judges only make ad hoc arguments to achieve whatever ends they desire, can they teach their class legal nihilism?
"Neutral" is the sort of thing that someone who has never actually tried to teach or inform can think is reasonable, until you actually try and do it and realize that there are people out there who strongly want to contest whether the earth is round, and that either you throw up your hands and accept epistemological nihilism or you accept that you have to pick sides, and try and do a good job of picking the right sides.
