Early on in the Vaush/Carl debate they get into a tussle around the appeal to authority fallacy. Vaush saying that its valid if the authority is an appropriate person to appeal to while Carl argues that its doesn't prove an argument. Carl is more correct in this case however.
What Vaush was contending is that the fallacy only applies in the case of appeals to non-authorities, which is true. But Carl's assertion that it doesn't prove an argument is malformed because he should be using the word valid.
And for Vaush to be so fucking cocksure and haughty over what he believed could be proved through a simple google search only for that to show Carl mostly in the fucking right, is embarrassing.

Hell without even looking at wikipedia we could use a more succinct source.
Literally all Carl had to do to btfo him was use the word
valid. This was dumb as fuck, Vaush.
