Jody, comments like those you made below reflect why these discussions go on so long: "To look at an animal and put our terms to them is wrong.... That is why I would rather see the animals called what they are and not what our terms limit them to."
Whose terms would you use? Do monitors speak English? What did Tyrannosaurus do, since in its entire existence as a living thing it had no name? You can't 'call them what they are' -- if monitors "know" each other at all, it's not a name but a smell! Seriously, any term only means what we humans agree that it means, and terms like 'social' are abstract concepts that are agreed to represent some set of conditions. DK and I use the term in the sense that biologists do, which probably differs from the sense of the term as understood by others.
One of the persistent lines of argument I see here is that since monitors do not always fight to the death or run each other off, they must be social to some degree. This confuses two things: sociality and territoriality. Territorial animals defend a resource, usually a patch of turf, and individuals that could threaten that possession are challenged, fought, and run off. The correct view, according to generations of lizard biologists, is that monitors are not territorial about home ranges, and therefore they don't engage in the sorts of displays and fights that we see in many other groups of lizards. Being non-territorial does not automatically make an animal social, but if monitors are not territorial it makes them appear less antisocial than are things that are chasing after each other all the time.
It turns out that this claim isn't quite true. I published evidence that male V. glebopalma are in fact strongly territorial, and have evidence that both male and female V. scalaris are also territorial. This is not what other lizard biologists expected to hear, but so far the evidence I presented has been accepted as documenting a first case of territorial behavior in monitors. The evidence for territoriality in V. scalaris isn't published yet, but when it is I am hopeful that it will be seen as a starting point for looking at other species more carefully. Using the same methods, I found that V. glauerti and V. tristis were not territorial.
First suggestion? You can't call animals what they are except by using human terms. Given that we haven't an alternative, we should of course try to use the most accurate human term we have, and if we're talking biology we should use the terms in the same ways that biologists do. Secondly, don't include hidden assumptions – animals can embody combinations of sociality and territoriality. Lions are social and territorial, leopards are nonsocial and territorial, bison are social and nonterritorial, and some (but apparently not all) monitors are nonsocial and nonterritorial.
