Let's stipulate for argument's sake you say something stupid or offensive or just something you didn't want to say. If your momma raised you right, you then say something like "I was wrong" or "I'm sorry, I shouldn't have said that".
But if you were raised by wolves or you have some congenital problem that makes it impossible for you to admit error, you say something along the lines of "I meant to do that!" or "No, YOU'RE wrong!" or "Jeez, but you're sensitive and politically correct."
This is what the young people on the Internets call "doubling down".
A few weeks back, Bill O'Reilly thought he completely pwned an atheist by saying that no one could explain the tides, and therefore God must exist. Stephen Colbert did an amazing smackdown of this with the aid of astrophysicist Neil DeGrasse Tyson. In the Colbert bit, his crack staff found footage that shows O'Reilly has been using this argument for years and years.
Okay, stupidity over. Done and done!
Not so fast, my friend. Remember earlier when I spoke of people raised by wolves or congenitally incapable of admitting error? Bill O'Reilly is the grand marshal of that parade.
Now that someone explained gravity and the moon to Bill, his next inexplicable miracle no human can explain is "How did the moon get there?"
Here's the thing. We are all ignorant of something. You kind of expect this of people who got third rate educations, like Sean Hannity and Glenn Beck. But Bill O'Reilly graduated Harvard and he's still this Sofa King stupid.
Guys like this make it harder for me to type the sentence "I believe in education". It also makes me wonder exactly how many classes he slept through on his way to his high school and college diplomas.
