LOL So much for scientific objectivity.
There is a place for saying an idea is dumb. When a child fears there is a monster under the bed, we help him understand on the basis of looking for evidence and give reassurances that he will be safe. When an adult fears monsters under the bed, we understand this as dumb and a need for psychiatric help. If I tell you that automobile engines work because of little faeries pushing the pistons, you would, correctly, say this is dumb. We reject lots of notions because they do not make sense. Every person is a mini-scientist.
Wolfgang Pauli once remarked, "Es ist nicht nur nicht richtig, es ist nicht nur falsch" --It is not only not right, it is not even wrong--in reply to some nonsense.
