A legal requirement to prove slander is that the alleged slanderer must believe that the accusation is false. Its the same defense that you use for your lies. Do you believe that I do not believe that you are spreading falsehoods?

Now that you know what I have told you about slander, to accuse me of it again would entail another lie.

That is the Truth of the Genesis creation story. Before man developed intelligence and morality, man was innocent of any action he took. But with knowledge comes responsibility. You cannot continue to claim ignorance of science after all of our sincere and patient efforts to educate you. Scientific debate cannot be honestly conducted without a basic knowledge of what science is.   Greg F's last link is very appropriate for this discussion.

It is extremely rude of you to figuratively cover your ears about what science is while constantly dipping into your well of pseudo-scientific, that is FAKE-scientific sounding nonsense.

It is dishonest for you to pretend that you consider that equal to science when you refuse to learn what science is.

You may think I am being less polite than Bill because Bill is being kind to you to appease your prejudices and save your feelings. That is probably true.

On the other hand. I would want someone to tell me if I was as clearly off base as you are. I cannot give you the comfort that Bill does. For one thing, I don't consider your purposely and dishonestly spreading nonsense to be a valid part of a civilized discussion. I believe that you are lying.
You have claimed ignorance far too many times to be credible. Willful ignorance is just another way to lie.
