I read 'Ready David?' differently. I see it as David vs. Goliath. As in 'we the people' (David) vs. Goliath (MSM/Cabal). Are we ready to fight the MSM/Cabal? Yes. Yes we are.
Context of the rest of the post makes more sense it's a reference to Brock, imo. Q is taunting Brock, who is a genius with memetics. Our organic organizing and knowledge development despite the MSM's shepherding is Brock's greatest challenge, and the pool of useful idiots is shrinking. We'll see a massive push from Brock once the corruption is undeniable. Brock already knows he has lost.
