Wronger than wrong

Something said with so much error that anything following it is an absurd conclusion.

This phrase's first known utterance was from Isaac Asimov.

"When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together." - Isaac Asimov

If you think that evolution means that monkeys should be turning into humans and that intelligent design is a scientific theory comparable to evolutionary theory then you are wronger than wrong.
