I have already explicitly stated that I am referring to arthropods and a handful of other invertebrates when saying bugs.
The argument on taxonomy and cladistics was started when Pelee cited that Lobsters are not classified as part of the category that is referred to as "True Bugs" in taxonomy. The Dinosaur argument came when he did not respond to my pointing out that by that logic a king crab isn't a crab becuase it's not part of the group taxonomically considered "true crabs."
