To give more context - this person is a “rebel canner” which means that they do things which are unsafe. The suggestion here is to go ahead and not use pressure canning techniques for things that need that, or water glassing eggs, because you can just cook out the botulism. The attitude is like if I was telling you to go ahead and eat that puffy can of ravioli.

Basically, it’s the type of conservative chud that acts like a toddler that feels the need to do what they’re told not to do.
