I don't need empathy. I have my pre-conceived notions that I will cling onto even in the face of all evidence to the contrary. Moreover, I will refuse to acknowledge the contributions of subject matter experts and science, even though I have no idea what I am talking about, because it is inconvenient. I do this so I can continue to make fun of people without feeling bad about myself in a consequence free environment. It is actually the only reason I even care about the issue: The freedom to continue to mock people.
