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".
It's just a word machine. There are no thoughts. It cannot be conscious. How is this even up for debate in any way whatsoever? I do not understand how people can believe this. Is this not a site for software engineers?
