This was said in a glib manner, which may be the reason for the downvotes, but it is completely true. This is how the Heterodox Academy defines itself:

>Heterodox Academy is a group of 4,100+ educators, administrators, & graduate students who believe diverse viewpoints & open inquiry are critical to research & learning. [1]

Does anyone think that a person who joins a group focusing on promoting "diverse viewpoints" is going to have a representative view of sharing controversial opinions? This is a wildly biased population of people to be answering this question.
