Would it be fair to you to tell everyone in every forum that you discuss, "No use talking to THAT guy, he has a pimple"?
But we're not discussing our complexions. We're discussing evolutionary science. So when someone claims the earth is flat it's a perfect reason to discount their understanding of the scientific method. I'm sure your complexion is lovely but your understanding of the world is severely deficient.
Your rants exemplify the truth of Chesterton's observati0n:
Every one who has had the misfortune to talk with people in the heart or on the edge of mental disorder, knows that their most sinister quality is a horrible clarity of detail; a connecting of one thing with another in a map more elaborate than a maze. If you argue with a madman, it is extremely probable that you will get the worst of it; for in many ways his mind moves all the quicker for not being delayed by the things that go with good judgment. He is not hampered by a sense of humour or by charity, or by the dumb certainties of experience. He is the more logical for losing certain sane affections. Indeed, the common phrase for insanity is in this respect a misleading one. The madman is not the man who has lost his reason. The madman is the man who has lost everything except his reason. The madman’s explanation of a thing is always complete, and often in a purely rational sense satisfactory.
