Frankly, it's getting more and more difficult to know if soemone is trolling or not about these topics. It looks like there are many people even here on HN who express similar views.
It's impossible to know for sure if someone is trolling by the original definition of the word. Since that refers to intent, you'd have to be a mind reader to decide it. In practice, it doesn't matter, because the effects of doing it accidentally are the same as doing it on purpose.
We mostly use the word 'flamebait' instead, which means approximately the same thing with the intent component taken out.
From a fire prevention point of view, negligence isn't different from arson, and it's a lot more common.
