The lack of testing doesn't prove the blue yeti doesn't exist either.Here is a demo of the warped logic caused by fallacy. He is saying that because there are no tests on bad bulbs, that proves their existence. LOL! Of course there are no tests, they don't exist!
Let me restate this to show how poor an argument this is:
"Can you show me a single test that was done on blue Yeti hair? You can't. Therefore blue Yetis exist".
