I don't think a lot of people speaking of free market have a deep knowledge about it. Arguing in that direction puts them in the uncomfortable situation of not having the words together to defend their side of the argument.
Try some tin foil hat argument about laying new cable being too expensive for the small guy, their internet ending controlled by "X" company CEO who may be part of "Z" cabal, and planted government moles not letting POTUS see the truth.
I'd think that would be a better follow up. Give them words for an argument then sidetrack the argument into tin foil hat theory that's easy to latch onto.
