I always kind of thought of myself as Neutral Good. I'm not a believer in rules for their own sake, but the good that comes from ignoring a rule should outweigh the harm incurred by surreptitiously changing the rules on everyone else. The most pernicious harms caused by breaking rules are the ones that aren't obvious, but rather confer an advantage to the parties that broke the rule that the rest of society can't easily detect, until those unscrupulous first movers have managed to roll the advantage up into a competitive moat.
I'm only commenting because I think it's interesting to think about why we think the things we do. I think it's a weird that anyone would want to fit an AD&D alignment onto me. :)
I can tell you why: You're clearly a (very) net positive contributor, however "strident" is a predictable default for any post of yours that's overly anything, combined with writing in a classical style.
Why people are trying to label you is you're hard to characterize yet are notably present.
I've been trying to think of a good label for him for a long time, and I think that hits it on the nose.
