Still not sure if this is a trend or if it's always been there to a certain degree and we're just more exposed to it with social media. I can't remember any professors that stood out as tribalistic SJW's who shouted down opposing views but that's obviously anecdotal.
http://quillette.com/2018/03/10/psychol ... hostility/The liberal philosopher John Stuart Mill once explained that, “The greatest orator, save one, of antiquity, has left it on record that he always studied his adversary’s case with as great, if not with still greater, intensity than even his own.” Mill held that unless we carefully study the views of those with whom we disagree, we will never really know what they’re right or wrong about. “He who knows only his own side of the case,” Mill wrote in his 1859 book On Liberty, “knows little of that.” Our opponents could be right for all we know or care, because they may know a fact or offer an argument we’ve never thought to consider. And even if they aren’t right, Mill points out that specks of truth may exist among their falsehoods which can guide our minds in new directions....
The world is more complex than we can imagine, and every new point of view we encounter can enrich our understanding even if we don’t embrace it entirely. But this comes with the risk of self-effacement and growing uncertainty. Imagine that you are standing in a small clearing in the middle of a vast forest, and that this forest represents your ignorance of the world. The clearing you stand in represents your knowledge. As one gains knowledge, the clearing expands and the forest of ignorance recedes. But as the clearing expands, so does its circumference and so the area of contact between knowledge and ignorance also grows, and our knowledge of the extent of our ignorance grows with it. So, paradoxically, the wiser we become, the less wise we feel. This is the wellspring of intellectual humility, the Socratic realization that the more you know, the more you realize you don’t know, and the more apparent it becomes that your own opinions are susceptible to fallibility.
This is a tremendous problem for progressive students entering higher education, where remarkably homogenous viewpoints are taught and heterogeneous ideas are shunned. For example, one of the concepts most ridiculed by philosophers in recent decades has been the notion of ‘social justice,’ which has received such a beating that the Nobel Prize winning economist and philosopher Friedrich von Hayek once remarked that shame should fall upon people who still defend the idea.2 But ask any self-described social justice advocate to name a critic of the very idea of social justice, and they will likely draw a blank. Criticisms of social justice are routinely swept under the carpet in an environment where students are asked to embrace the concept hand-on-heart, as if no reasonable or legitimate objections had ever existed.
