Like almost everyone commenting on this, if they aren't missing the point intentionally (controlled opposition), they are pretty dense. The regulatory tools to deal with FB et al exist and are pro-liberty. Supporting free markets means opposing monopolies. Supporting free markets means corps are responsible for the shit they put on the Internet. Break up these monopolies now (in addition to what you said). If any regulators had any balls it would be done already. Congress can order regulators to act, if necessary.
