He just said he is negotiating with Iran, which Iran is publicly refuting

This talking point is going over like a lead balloon on T_D. The removal of downvotes means "dissenting" posters can point these things out without being downvoted into oblivion, however that just means various users are going full copium and trying to dismiss such posts as shills, propaganda, bots, and the like.

It's ironic that in an attempt to hide just how many aren't on board with the current Iran situation all the site did in the end was stop them being brigaded for jumping on the bandwagon blindly.
