Why is somebody always fired after a Breitbart video is put on the Internet or Fox News?

Breitbart makes obviously edited video
Person who is 'star' of obviously edited video loses job that was a lifelong career
It then comes out just how obviously edited the video was, often what was really said was the exact opposite of what's in the video

This seems to be the standard formula for a Breitbart smear operation.

Now, you give a frog a bee and when it tries eat it, it'll get stung. But it will learn pretty quickly to stop trying to eat bees. That's right, amphibians are at a faster learning curve than us. Scary.

This goes to show that the real villain here isn't Breitbart, it's our culture and our media. If Breitbart's cut-and-paste videos can repeatedly stir the people to kick people out of lifelong careers, then what is the upper limit of this? What would people more skilled and charismatic than Breitbart be capable of?
