I find it depressing that this post from Raph was even made. To me, it is like the following:
Professor Raph walks into the room. He writes on the giant black board, "advanced cellular biology". The students watch, pulling out their notes.
Raph: "Cellular biology explores the foundation of life itself. This is the field which allows us to manage bacteria, virii, cancers, drugs, and even genetic engineering, in addition to simpler things such as proving that grass and trees are in the same kingdom. In this advanced course, we'll be first learning how to monitor retroviral-"
Student: "Wait, grass and trees are in the same kingdom?"
Raph: "Uh... yes. Yes, they are."
Student: "I don't believe you."
