The ozone layer has a naturally occurring hole that may serve a purpose. It gets bigger and smaller as some sort of natural occurrence and there's nothing we can do to stop it or change it.
The ozone hole was not there in 1956. It's not natural.
The dirty hippies pointed out the problem, and got the fix in place. The dirty hippies saved your ass here. Show some gratitude.
This is a lot like the kooks who think the Y2K issue was all a conspiracy. Many thousands of people busted their butts to fix the problem. And since they fixed the problem ... it proves that the problem never existed! Take that, dirty liberals!
Denying CFC-caused ozone depletion is like denying that smoking causes cancer. Not surprisingly, the same group of paid shills worked hard to deny both. And that exact same group of paid shills, literally the very same people, are now being paid to deny AGW.
