"The unbridgeable chasm between your view of the world, and mine, is that my knowledge and experience allow for the classification of BF as something very mundane in the context of human experience and biology. Yours (and several others' around here) allows you to see it as something exotic to the point of being an unacceptable hypothesis." WSA
Who is calling bigfoot an unacceptable hypothesis? It is unproven without physical evidence, except, of course, to you and others here. But that does not make the hypothesis itself as unacceptable. Any hypothesis is acceptable. Proving it is a different matter.
