hiflier, I don't know if you've had any encounters of your own, but I've had several. We agree that they are omnivores and we agree that they need a lot to eat every day, but your ASSumption that they are universally benign creatures is faulty. I perceive them as continuously hungry, continuously in search of immediate, or future, food sources. I perceive the primary reason that they lurk around us as food related, not curiosity. Yes, they are curious, but food will always be a prime consideration in their minds. As I've stated, they think, reason, and choose courses of action based on the situation.
They do eat as much meat as they can get their hands on. They have to in order to support their muscle mass and cranial development. They need high protein intake and would not be what they are without it. THIS is also nature.
They are top predators. Their lurking behavior is no different than that of a tiger, a wolf, a bear, or child molester. I have on two occasions been in situations where they have attempted TO DRIVE PEOPLE AWAY from food that they were cooking. Food that was not harvested from the environment, food that they had brought with them and were preparing.
In another encounter, one had its arm in our tent trying to take a dog from us when it woke me up. I also believe that if my brother and I had run as the male that confronted us expected, it may well have taken Dave. I don't know if "zapping" is something they actually do, but I do know that from a biomechanical standpoint it is possible. The adult male that fully exposed itself in broad daylight had no need to do so if all it wanted to do was avoid us. It, and any others with it, could have slipped away to the South without any of us ever knowing that they were there. Instead, it presented itself and it sure didn't act curious. It seemed stern and annoyed when my brother and I didn't run, then briefly cautious, then disinterested. It was as if it were thinking, "are you really going to stand up to me?", then "do they have some ability to injure me that I can't see?", then "don't bother, I really don't want him anyway."
I could go on about food related encounters and being stalked while fishing. WE ARE A SOURCE OF FOOD. We make kills, fish for, gather, collect and store food that they steal, we plant, grow, breed, husband, and harvest food that they pilfer. We provide in plenty food sources with vital nutrients that they cannot easily find in large quantities, and we cook it, creating aromas that apparently inspire them to attempt to drive us away from the food at times. And in a pinch, it would not surprise me in the least if they grab a wandering child from inattentive parents or an isolated cross-country skier during a harsh winter. If a bigfoot wants something and feels that it can take it with impunity, then it likely will. Who's going to stop it if we aren't paying attention, don't see it, or no one else is around to stand up to it?
You are entitled to your platitudes, but you're wasting your time if you believe you can sway me from my own experiences.
