No, you didn't give me the impression that they were rude. I'm saying that your departure from BFF was a non sequiter. IOW, it doesn't make sense why you stopped conversing with the Bigfooters at BFF. You say it was because "your Bigfoot" wasn't like "their Bigfoot". But that isn't even true. You never even gave anyone a chance to say something like "Gosh, your road runner thing doesn't really sound like a Bigfoot". No, in fact, listing the physical characteristics as above (7'+, fully hairy body, running biped) - I would bet anything that virtually all of the Bigfooters would have insisted that you did see a Bigfoot. It would make no difference if you said it was more ape-like than human-like or vice-versa. A nocturnal seven foot hairy running biped is going to be Bigfoot as far as they are concerned.
William Parcher, perhaps they would have immediately confirmed it was a "bigfoot" as far as they were concerned, but I was trying to *not* automatically see it as a "bigfoot". It was something, it was alive...it was on two legs, but, it *could have been* something else. Like I said, I'm not a "bigfooter". I more consider the probability that it *was* something else, but have been unable to dismiss the possibility that it could have been what is commonly referred to as a bigfoot. Maybe that doesn't make sense.
Oh, and Vortigern99, I hadn't considered a hoaxer but yes, there's no way I could dismiss that possibility either. (Sorry, forgot to add that)
