Actually, what I tend to find is that they're just deliberately ignorant because they're scared of challenges to their beliefs.
See? I can make sweeping generalizations, too.
Who is it that's afraid of having their beliefs challenged in this case? A handful of self-appointed philosophers who clothe themselseves under the garb of "science." Dogmatists staunch in their faith and blind in their zeal, not unlike Spanish Inquisition types. Let them have their philosophy and teach it, but don't expect the rest of the world to swallow it as "science."
