The inspiration for this article is backwards. I saw a rant in an inconsequential forum by a vituperative but unimportant atheist. Then I read the article on one of the sites I subscribe to that brought his childish "you deny evolution and billions of years, so you're a liar" reaction. The article in question is by former theistic evolutionist Dr. David Catchpoole of CMI, "Faith can move mountains (but it can't change history)". He wrote a short article about the global Genesis Flood from his biblical creationist (young earth) perspective, and was given an ad hominem attack for his efforts by the aforementioned atheopath.
Dr. Catchpoole gave links in that article to some of the science articles supporting the Genesis Flood, but the critic did not seem to be interested in reading or responding to those.
The uneducated atheopath railed against Catchpoole, displaying his inability to distinguish between a different interpretation of evidence and a lie (plus being intolerant of people for even having a non-evolutionary viewpoint). This shows something that I have been saying for years: Hate stupidifies. (Stupidify is a word I picked up from Matt Slick of CARM.) This fits with something that some theologians call the "noetic effect of sin", where God essentially says, "Enough! Have it your way, I won't contend with you any longer" (Romans 1.24-25). The point is that sin corrupts all aspects of someone's life, including the ability to reason. They think they can cogitate on something and be brilliant, but they really can't think well at all.
I've seen it. Some people can carry on a conversation, offer analysis of situations or observed facts, and so on. When it comes to matters of morality, theology and so on, their nice horsie of thought suddenly throws them from the saddle. What baffles me is that people make the most basic errors of logic, and are so consumed with hate that they do not make sense, and cannot be schooled in the most basic principles. I have pointed out the errors of some people, and then they justified their bad logic by doing the same things again, and they consider personal attacks to be "rational arguments"! God is right, they claim to be brilliant, but that's not the case (Romans 1.22). Worse, others who are in agreement with their hatred of God and excuses to reject him applaud the bad logic (Romans 1.32).
Many obstreperous atheists seem to think that they have a crusade to protect "science" and "reason" from "religion". What they are really doing is spreading hatred, bad logic and bigotry. If they want to have a purpose, get on God's side and fight for what is right. Someone rightly said, "If you want to rebel against someone, rebel against the devil!" That's true, since he is their master.
It is clear that true "freethinkers" are not atheists who believe they are intellectual. They are rebelling against God and are actually under the control of Satan (2 Corinthians 4.4, John 8.44). True free thinking comes through something that is irrational to them, and that is through submission to God (Proverbs 1.7). Until they repent and make Jesus Christ the Lord of their lives and thinking, they remain fools (Psalm 53.1) under their master's control. Addendum: An excellent article on a Christian view of the intellect is here.
