Re: Laughter is the appropriate response when someone asserts a Biblical Flood happened.
Correct. 2 Peter was the first major crisis when Christianity had to recognize the fact that what Jesus supposedly said was simply wrong, simply false. While admitting Jesus had been wrong the author of 2 Peter created the career of the Apologist; the Wizard of Oz behind the curtain who made up stories to try to pretend the Bible stories were simply often factually wrong.
I have been giving this a bit a thought and would like to break it down slightly differently:
Five types of people that don't understand how evolution/biology/science work:
people too stupid to understand the concepts. These are the unfortunates. It is not their fault.
people ignorant of the concepts, possibly through no fault of their own. These are the fortunates -- they can be cured via education. A good starting source is Berkeley: Evolution 101.
people that have been misinformed. These are the deceived. It may be possible to cure them with education, however the victims need to be willing to learn, and willing to give up the false concepts they have regarding how evolution/biology/science work. Cognitive dissonance comes into play here when this affects core beliefs that are strongly held.
people who are charlatans. These are the people that do the deceiving of others. These are the deplorables. They too can be deceived (and likely deceive themselves), however they continue to present falsehoods even when they have been corrected. Trolls also fit in this category.
people who are clinically insane. These are also unfortunates, as it is not their fault.
Rejecting information does not refute it, that just puts you in one of the 5 categories above.
I think you need an additional category for those that hold a belief that makes it impossible for them to accept an idea that contradicts it.
They're not necessarily insane, not necessarily stupid or ignorant nor necessarily misinformed, they just can't allow anything to interfere with their belief. Deluded is one word for it but that refers to their belief, not to, for example dating methods or the ToE - they simply reject them out of hand.
