I think people like to argue about things. That's not necessarily indicative or real world issues.I don’t personally think it’s very useful for that. We have much better RP aid tools that don’t cause arguments like alignment does.
Do you not consider these threads that pop up every few days, devolve into bickering, and then get locked problems? Also, just because it has been 20 years since you had a an argument about alignment in person doesn’t mean this isn’t a more recent occurrence for other people. Any time you try to hard-code moral judgment like “good” and “evil” into the rules of the game, you’re going to cause arguments.
In any case, I just don't see why it's a big issue when it can be completely ignored and people say that it's completely "broken" because some people somewhere said something they disagree with.
But I'm done with this. I primarily was commenting that the removal of default alignment at this time only applies to PC races and is not applied across the board.
