I've gotten into it with "Professor Dave" on YouTube. His EU video is friendly and cute, but it is a hit piece, pure and simple. The guy in real life, however, is neither friendly nor cute. He is vile. Check out his YouTube comments section to see his litany of condescending, vulgar responses to anyone questioning his limitless knowledge. He's a high school science teacher, for god's sake. Hardly a pedestal high enough to rain down insults on those who don't believe in his special brand of unfalsifiable and undetectable magic (i.e. black holes, dark matter, big bangs, Oort clouds).
Dave's debunking video basically comes down to this: EU guys think electricity is more important than gravity, but gravity is all we see in the universe (or think we see), so they're crazy.
