I'm tired, pissy, unstable, and supposed to be in bed right now, so I'm going to make this one short and sweet.
Cryptozoology is not the study of things that don't exist. Cryptozoology is the study of hidden (otherwise known as "unclassified," "undiscovered," and "not yet cataloged") things.
Either learn this, or stop trying to have a conversation about cryptozoology. Thank you.
