You're seriously accusing others of Zeal? Do you have no mirrors in your home?
Reality check, mate. You're trying to say that legends in other cultures are a mythological animal, and you're basing that purely off of personal preference and wishful thinking, given you have no actual bigfoot and have no way of knowing what specifically a bigfoot is or what it does. How do you know it doesn't burrow and live its entire life under ground? How do you know it's not purely a quadruped? You don't, because nobody has ever had one to study, and likely never will.
Your entire argument is wishful thinking and personal preference. Reality has no part of it. And you're fueling your entire argument with nothing but zeal.
So, please. We're trying to be kind here. There's no cause for you to carry that armload of rocks into that glass house.
