It is not so much an accusation that the other party has become too emotional as an admission that the "situation" is becoming too driven by emotion. The suggestion is for a postponement of the matter. The matter is indeed to be discussed, but at a later date. There is some overlap with 6/3 in the sense that a future discussion is promised. The emphasis, however, is on the emotional aspects which would prevent a reasoned consideration of the matter. It is important to accept that the code is not an "accusation" ( even where this might be justified) but an acknowledgement that an emotional atmosphere is making the situation more difficult.
