If we want to see the Democrats do this we will need them not merely to start combatting GOP messaging but to stop fucking _amplifying_ it. Enough is enough of Democrats embracing racism, transphobia, Islamophobia, anti-abortion, etc.
What's striking to me are the rules of engagement and the methodology of action here, which more or less is predicated on burying liberal delusions about "debate" or the "marketplace of ideas". The rules were ultimately very simple: amplify your own message and suppress your opponent's.
