Move the needle means have an effect on public discourse and influence natural social media chatter. That Q post sounds like a spookjob to stop people taking justice into their own hands though ("Save the taxpayers some money" = Kill some of these evil motherfuckers). Don't like that kind of bullshit, particularly when we're not seeing institutional justice standards being met. Only a lot of drawn out inconclusive "process" theater. This is playing too much into the "Q is just there to stop normies taking citizen's action" side of the debate. Edit: okay, I will add that there is some discussion that Q could be referring to possible suicides within cabal ranks to "escape justice". So perhaps God will get an express delivery of assholes this weekend.
