This isn't an example of fulminating, please don't incorrectly quote the hacker news guidelines at people. We strive for curious discussion here.

An example of fulminating would be: How dare you accuse him of fulminating? That is the most ass backwards moderating I have ever seen! Do you even know the definition of the word? Who paid you to call him out?

His comment may be sarcastic but it is not "fulminating".
