IMO it is better not to assume a comment is trying to support one of two sides of an argument. For example, it might be critiquing the general way the argument has been framed (where the line’s been drawn between the two sides), or the method of making the argument (if everyone is sitting around looking at some obviously incomplete data and trying to tweak it to push their point, it is worth pointing out that whatever conclusion the group comes to is probably meaningless). Or it could just the a bit vague and hard to interpret.
