I think the breakdown here is that conversation seems to have no power. To only be a bit hyperbolic, the only language with power is money -- or violence. To the extent that ordinary people cannot make change with "conversation" (which I interpret here to mean dialog within society, including with lawmakers), they feel compelled to use violence instead.
A non-rhetorical question: What recourse to non-billionaires have when conversation has less and less power, while money has more and more, and those with money are making much more money?
Michelle Obama's, "When they go low, we go high", is some of the stupidest political advice and a generation has lost so much because of it. (The generation before got West Winged into believing the same thing.)
When you look to the right, you have a stolen election in 2000, a stolen supreme court seat, an attempted coup, and relentless winning despite it.
But it seems a distant hope at best.
