Well, insane, probably not in most cases. I prefer the term deluded. Stupid? Ignorant more like it. When the evolution myth is promoted exclusively in all educational facilities and the Creation account dismissed as "religion", I expect little else. You think that the quoted interview is the only reason? There is vastly more.
Evidence is in the eye of the beholder when it comes to evolution. I see the incredible creative power of God in everything that I see. Evolutionists see nothing but a random number of molecules that somehow assemble themselves into amazing complex creatures that is far beyond anything that mankind can create.
If you evolved, then your life is meaningless. Your thoughts are completely programmed and you have no choice. You are entirely at the mercy of forces beyond your control.
