Specifically, I think these three paragraphs near the end are critical:
> I'm reading a great book now called Why People Believe Weird Things, by Micheal Shermer, in which the author explains what rational thinking is, and how skepticism is a process. Basically, people believe something because that want to, not because of any scientific arguments you make.
> There are guys out there who dislike Ada, but they do so because they want to, not because of any rational analysis of its merits or flaws. Sometimes even their arguments are factually incorrect, like saying that "Ada was designed by committee," ignoring the fact that Jean vetoed language design arguments that were 12-to-1 against him. It's not unlike creationists who explain the "fact" that evolution violates the 2nd law of thermodynamics. (No, it does not, as any book on freshman physics will tell you.)
> I've explained the reasons Ada why I think is not as popular as C++, and I'd like to hope that it will convince Ada's detractors that Ada isn't so bad after all. But as Robert Dewar pointed out, a person who has made an irrational decision probably isn't going to be swayed by rational arguments!
That is, people aren't really rational. A choice was made to dislike it, it entered into the culture and to this day people dislike it because they think they should dislike it. They don't even spend 5 minutes studying it to see that half of what they've heard (if not more) is flat out wrong. In several Ada discussions on HN people claim its syntax is like COBOL's, for instance. Not just similar in being keyword heavy, but practically the same. Sometimes they even provide Ada "examples" that won't even compile. That's the kind of nonsense that happens when people turn off their brains or refuse to turn on their brains. You see it in many Lisp discussions as well.
