It depends on the reasons why one considers it right to benefit one's own faction and defeat opposing ones, I guess. Or are you proposing that this is just taken as a basic premise of the moral theory? If so, I'm not sure you can justifiably attribute it to many political groups. I doubt a significant number of them want to defeat opposing factions simply because they consider that the right thing to do (irrespective of what those factions believe or do).
Also, deontology, consequentialism and virtue ethics count as object-level ethical theories, I think, not meta-ethical theories. Examples of meta-ethical theories would be intuitionism (we know what is right or wrong through some faculty of moral intuition), naturalism (moral facts reduce to natural facts) and moral skepticism (there are no moral facts).
Okay... wow. I somehow managed to get that wrong for all this time? Oh dear.
This one isn't ever formal and rarely meta-ed about, and it's far from universal in highly combative political groups. But it seems distinct from deontologists who think it right to defeat your enemies, and from consequentialists who think it beneficial to defeat their enemies.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
