You know someone's a crackpot when you're at an undergraduate level and you can still see how wrong they are. Like, using basic terminology incorrectly and everything. The whole works. It's facepalm-worthy. How do you deal with that? I mean, I can't just ignore it when this person is broadcasting their "knowledge" on social media--in a group dedicated to rational discourse, no less!--and could very well lead unsuspecting people astray, because his rhetoric is just "scientific" enough to sound legit to the uninitiated. His disorganized delivery might be enough to ward people off, but I can't be sure. Yet, I don't want to start the equivalent of a digital barfight.
