Congratulations on stating the obvious....
If it's obvious that within guidelines of this forum wannaexit does have purview to share opinions, including a recommendation that the group should move on for whatever, then your objection to what wannaexit said is baseless. That is to say, contrary to your earlier directly relevant assertion to wannaexit statement at issue that "It's also not your purview to tell everyone else what to do" it turns out that, according to you, it's obvious that wannaexit does in fact have the purview you said she/he did not have.
So which is obvious? That wannaexit has or does not have purview to share an opinion as a recommendation that the group should move on? You've asserted both!
