It's that i used the word fallacy. I really don't know why he doesn't hear it continuously from everyone he meets and reverberating in his head.
He does hear it quite often, but not everyone learned logic. It's really not taught well in schools, and finding good books on the topic on your own can be quite difficult, even despite the number of programmers out there. Most of the logic illiteracy centers around set logic, not usually represented well in programming languages. I have found a fair number of programmers that don't even understand combinatoral logic. Many can't code their way out of a wet paper bag. Even AI can do a better job then they can do themselves.
Schools do a bit better job on mathematics, but it's really only basic stuff. There are a lot of people around that have no idea of even trigonometry, probability math, or statistical math. Casinos make a lot of money out of such people. Such are also susceptible to any random number quoted by the government as 'data'...something that governments do constantly. Like Las Vegas, they know they can take advantage of the mathematical illiteracy out there.
The word 'fallacy' DOES ring in their head. You can tell this because of the string of insults and mimicry whenever I call them on one that can last for months (insults without an argument is just a void, therefore a fallacy).
In the War Zone, you will find a thread called the Monthly Contest, which I run (though I havern't run it lately). I've explained the background to some fallacies in there. Occasionally, I also explain one when I call some idiot on it, but of course they deny it all. Such explanations are usually for others watching the thread and are willing to learn. As you can imagine, here on JPP, it's not that many.
So usually I just call them on the fallacy without further explanation. It's terse because I have to be so repetitive. You will often see me use a couple of acronyms:
LIF: Lame Inversion Fallacy. This is just an inversion fallacy that is particularly lame. Usually it forms when someone tries (badly) to mimic. It's the argument technique of a little child (around 3-5 yrs). The inversion fallacy itself is also called Projection. It is blaming their own problems upon another, effectively inverting the rolls. A LIF occurs when one simply trades words like an old Dr Psycho game to conduct the fallacy. I find this tends to occur more when I call them on an inversion fallacy in the first place, and they begin using this childish technique. (A->B = B->A)
RQAA: Repetitive Question Already Answered. This is exactly what it is. It often occurs when the answer is not liked by this type of idiot and they continually ask the question over and over. It's also a childish technique, similar to asking the other parent when the first one says No. The difference is they keep asking the SAME parent, trying to wear them down. You will find some users here particularly prone to this practice. It's a form of a repetition fallacy. (?A->A->A->A->A->A->A->A->A->...)
You seem willing to learn this stuff, so I will explain for you more often.
