WTH is Scotty Kilmer's problem, anyway?

Here he is showing viewers how to do an unsafe brake line repair:



Wow. What an idiot. At first I was going to disagree with you, because before I started the video, it appeared the union he used was a double flare union, which would have been completely acceptable. After watching though, I see he used a ferrell union. What an idiot. Those things are not designed to handle the kind of pressure brake lines carry.
