I got the impression fairly early on that around here skepticism can be carried just so far. A poster once wrote that he abhors Muslims, hates Jews, reviles Catholics and can not stand Protestants. Further, Arab men disgust him and he would be very happy see them wiped from the face of the earth.
I responded that, quite frankly, I considered the poster to be an absolute raving maniac and was quickly yellow carded for being uncivil and attacking the arguer not the argument.
Only...
What was the argument? The poster was expressing a personal belief, weren't they? They didn't include any evidence showing, I don't know, why Arab men -- or at least the average Arab man -- were objectively disgusting. Why Muslims were abhorrent or Jews deserved to be hated. He just stated it. I guess I could have just stated I didn't agree, but that's not much of an counter-argument. Wasn't I really arguing that the level of hate expressed in the post -- reviling, hating and being disgusted by perfect strangers based on their ethnicity or religious beliefs -- wasn't a rational argument? That the argument was one that, by most standards, would be considered unhinged?
How would I have gone about attacking his "argument," anyway. Cite studies showing Arab men are not disgusting? That Jews, Catholics and Protestants as a group are quite likable? It seemed more honest -- and a lot more on point -- to dismiss the argument as maniacal.
If someone states a personal belief does questioning it become off-limits? (You can attack an argument but never an arguer.) But how could that be on a so-called skeptics forum? What if the personal belief was to just state that the person believes the Earth is flat. Would it be permissible to say, "No it's not flat," and possibly link to photos of the Earth taken from the Space Station? Aren't you still attacking their personal belief? What if they responded by writing, "I don't care what those (probably doctored) photos show; I believe the Earth is flat." Could you just respond, "Then you're an idiot?" Wouldn't someone who sincerely thinks the Earth is flat, thinks NASA photos are fraudulent, fall within the broadly accepted definition of the word, "idiot?" In the same way someone who hates, reviles, can't stand and is disgusted by nearly half the Earth's population fits the broadly accepted definition of the phrase, "raving maniac?"

What if thinking that is my personal belief?
Could I have gotten away with it if I had been careful to write, "That's an argument only a raving maniac would make?"
As a great man once said, "So many questions, so little time."
