From the Atheist Ethicist:
I have a special way of knowing things.
This special way of knowing is not subject to proof of any kind. These facts exist outside of any realm touched by reason or demonstration. I simply know them. God must have planted the knowledge of these things into my head directly. Since God would not deceive me, I trust these facts beyond all reason. I can trust God because this is one of the unquestionable facts that God has placed in my head.
These facts that I know that are beyond all reason are moral facts. They are facts about who I may kill, who I may maim, who I may imprison, and who I may enslave. They are facts about what I may do to women, what I may do to homosexuals, and what I may do to those who do not believe.
When I come to kill or maim or imprison or enslave you, do not ask me to justify my actions. My actions are self-justified. They come from my special way of knowing that is beyond inquiry – beyond reason.
If you deny that I have this special way of knowing, if you deny that I may kill, maim, imprison, or enslave those that I know I may kill, maim, imprison, or enslave, then you are insulting my beliefs – and that is something I will not tolerate. I do not have to tolerate your insults because my special way of knowing tells me that I do not have to tolerate your insults.
Do not question how I treat women, because in doing so you insult my beliefs.
Do not question my attitude towards or treatment of homosexuals, because that is also an insult to my beliefs.
Do not question my distrust of those who do not believe as I do, because by their mere existence they insult my beliefs.
Do not question me in any way, because to question me is to insult me.
In case you have not figured it out, my special way of knowing also tells me who you may kill, maim, imprison, or enslave. It tells me what you may wear, who you may be alone with, what you may say, and who you may have sex with. If you disobey any of these rules that my special way of knowing gives me, then you have insulted me and my beliefs.
Of course, my special way of knowing tells me what you may say with respect to questioning the facts that I know beyond all reason through my special way of knowing. You should be clear on that matter by now. I will expect you to comply and I will respond in a way that my special way if knowing tells me is appropriate if you do not.
Everything above this point is satire. But, I hold that it represents a very common way of thinking – and a very dangerous way of thinking. While not everybody thinks this way (obviously) we clearly have a lot of people who are far too close to this way of thinking – even if they do not put it exactly this way.
