> adequately explained by stupidity

What is the adequate explanation via stupidity in this case though? If there is one that sure maybe we should lean that way without further evidence.

Keep word: adequately. This is not adequately explained by stupidity.

It does occur to me that you can be both malicious and stupid at the same time.

This gets complicated when the malicious have also read the saying and intentionally feign stupidity, but that's just chaos politics.
