One concern I have is the phrase "explicitly honour" in "we explicitly honour diversity in: age, culture, ...".  Honour is a curious word choice.  honour is defined as, among other things, "to worship", "high public esteem; fame; glory", and "a source of credit or distinction".  I would object to some of those interpretations.  Also its not clear to me how honouring diversity relates to conduct.  I would definitely agree to follow the other parts of the CoC and also to welcome others regardless of where they fall on the various axes of diversity.  "Explicitly welcome" is better and much more closely related to conduct IMO.
