That story about the bumblebee turns out to be an urban myth, which is rather disappointing. Ah well. Nobody likes to be told that their cherished beliefs are wrong, but the answer to that is not to make personal attacks on the messenger, but to disprove, if they can, the message. Unfortunately, that is often too much like hard work; and an anti-intellectual rant will always attract some support, though it won't change the facts.
