Interpretations of what's uncivil differ, of course, but we ban accounts that snark like this repeatedly:

That's a long way from just telling someone they're wrong—which, btw, by itself isn't that substantive in the first place. Explaining how they're wrong is much better, because then the rest of us can learn something. But presumably this is what you meant. You've posted a bunch of substantive comments that are just fine for HN, so whatever the above issue is should be easy to fix.
