A. Infowars does not have the footprint or influence of CNN. Except for the MSM ya-ya, the vast majority of Americans would not have heard Jones' opinions on this matter or much of anything else.

The parents will have the satisfaction of bankrupting the company, but other than shutting Jones up on this subject, what did they accomplish? Nutters gotta nut, on either end of the political spectrum. He makes his living off of agitprop.
He will continue to do so.
