Whether individuals that post to the SegWit2x mailing list express the desire to “fire core” (which I personally subscribe to) does not affect the NYA WG terms of reference that are to not split the NETWORK. You can safely assume that the intention not to split the COMMUNITY is derived from the TOR of the WG.
Conceptually, the list is for development and therefore discussions held there, if adopted, are meant to be reflected in the client code. Opinions expressed are neither binding on the end product nor the WG TOR. This must be clear to you yet, like a certain group of devs, you chose to label the “claims” a lie for nefarious reasons.
Anyway, here’s a link to the mailing list.
