I know for a fact that my wife is afraid of the remote possibility of a bigfoot encounter, and I'm pretty sure my daughters are, too. And a man discouraged me from telling bigfoot stories to his kids (even though that's exactly what they repeatedly asked me for) because he didn't want them to be afraid in the woods. I've also read multiple admissions from grown, armed men on outdoor hunting forums that a bigfoot encounter would scare them.
I agree that many ridicule sasquatchery based upon the official rejection of the phenomenon by the science industry, and I agree that hoaxes are extremely counter productive and add to the ridicule, but that is clearly not the only reason. "Only reasons" are more rare than sasquatches.
Actually, sasquatchery has high acceptance among the dreamer crowd. We've seen overwhelming evidence of that right here on this forum. Harry and the Hendersons created an entirely new class of sasquatch acceptance among the ignorant, and much of that was by eliminating the fear. Make sasquatches friendly, non-violent, fun, and loving, and the dreamers will climb aboard.
At least for those who haven't had a sasquatch in their face. There are differing levels of acceptance, doubt, rejection, and denial. Those who had close encounters with a sasquatch go well beyond "belief".
