They think that way. Such militant ignorance is hard to deal with. I once got into a "discussion" with some lame brain here on FR who was convinced that there were such things as 100mpg carburetors. When I told him that the laws of thermodynamics precluded the existence of something like that he said well that's just your opinion, and insisted that his opinion was a good as mine - mainly because he didn't have a clue about energy and the first and second laws. Well it wasn't my opinion it was the first and second law, and his ideas were just flat out wrong, but he was too set in his ideas to admit that someone else might know more about than he did. I gave up.
