I think what you're describing here is that moderation on ENWorld has always been reactionary. This is not a critique; it's a logistic necessity based on the size of the community, the size of the mod team, and the reality of living in a changing society. This has a couple of important effects to consider.
First, it means that the mods are more concerned with doing the right thing than being perfectly consistent.
There was, a while back now, an instance in which someone came in with a novel approach to making people uncomfortable, one we actually hadn't seen before. The Rules didn't really preclude it. Morrus wasn't around, so I couldn't ask him how he wanted it handled.
I chose to remain consistent with the rules we had, rather than to make new precedent. The result was some folks getting away with saying a bunch of really hurtful things, and my defending their right to do so. It felt horrible, and I have no doubt that several people lost respect for me - I know a couple of users left the site over it. I am not proud of that moment, and I have been sorry for it ever since.
So, yes, sometimes consistency is in conflict with being on the right side of an issue. And these days, when they are in conflict, I try to err on the side of right action, instead of consistent action.
