I thought agreeing/respectful posts by non-Caucus members were tolerated on Caucus threads as well. Otherwise, there’s a post above by an agnostic that needs to be removed as well.
But when a non-caucus member crashes through the closed doors or is otherwise not welcome (pings to the mods, abuse reports, Freepmails etc.) - his posts will be removed and he will be "invited" to leave.
