Ideas have consequences. So do attitudes.
Famous Christian scholar, C.S. Lewis, long supported the idea of theistic evolution, but changed his mind later in life. He said:
“I wish I were younger. What inclines me now to think you may be right in regarding it [evolution] as the central and radical lie in the whole web of falsehood that now governs our lives is not so much your arguments against it as the fanatical and twisted attitudes of its defenders.”
