He is angry, and he's correct.

He lets his anger sweep him to saying incorrect things inside the overall correct thing he's saying.

This gives people who don't want to know that his big observation is correct a fairly easy way to scurry away from it.

The more the big anger matters, teh more the smaller errors are a disservice to humanity's group learning.

The more the someone else's big anger matters, the more I should hang with learning from it and not take the smaller errors as an excuse to got back to sleep.
