Official Clarity Necessary
Expressions that any reasonable person would find offensive.
This is my only real, "big," thing that needs to be changed/removed. The fact of the matter is that, "Reasonable," is extremely subjective and everyone has a wide and varying degree on what they consider offensive or inoffensive. Leaving it up to GMs means leaving it up to their bias (and yes, it's biased, as they must decide for themselves whether or not they personally would find the comment(s) offensive).
While I'm sure that this policy was put into place with good intentions, it's easily abused, and it's easily misrepresented by new and old GMs alike (language barriers, tolerance levels, management environment, etc). Ultimately, I think this point, in particular, should be removed (as many other points already cover offensive behaviors that would fold into this rule).
Expressions that unilaterally reject another person's opinion.
Unilaterally: used to indicate that something is done by only one person, group, or country involved in a situation, without the agreement of others.
I think this particular bulletpoint just needs better phrasing. There's a reason people are misinterpreting this to be, 'You can't have disagreements anymore!' Different playstyles exist depending on difficulty and preferences. And there are plenty of "hot topic" debates about what "is" and "isn't" acceptable to do in XYZ situation (everyone remembers the Cleric Stance discussion). And that's just tackling game-related things and not the plethora of conversations/debates that happen online. If someone comes in and says, "No, I think X way of playing is wrong/ineffective/etc," this phrasing leaves it open that they could be banned for it. It's just messy and I think the phrasing could be cleared up.
Expression that contravene public order and morals.
This is another one I know came from a good place but definitely needs clarity. Given the political state of some places XIV is housed in, this is a policy that gets messy real fast. Also, the use of "morals," here is probably unnecessary and is a major grey area.
Ultimately, I think a lot of the changes were necessary and I'm thankful for them. But, I think that this update needs a "hot fix" on terminology and possible removal of expressions that any reasonable person would find offensive.
