I honestly can't for the life of me understand what you're trying to say here.

The poster said "They're more carbon neutral than dino diesel."

I was simply stating that not only was I not arguing otherwise (if we're assuming "more carbon neutral" means better for the environment), but also clarifying what the term means (the binary state of being carbon neutral).

I think your statement was unfunny because I did not personally find it funny, nor do I expect others to. Not for any other nefarious reason.
