One of the easiest ways to counter this rhetoric is to point out that the violence is never gone in whatever state system exists. Any threat, from a historical pov, is met with real violence and the liberal idea of truly free speech only exists in a state where there exists little to no current threat to the underlying power structure.
For conservatives (especially the kind that believe that socialist/etc will concentrate too much power in the state, whi h will result in state violence) you need only dig down a bit to get them to admit that they believe that violence is appropriate so long as it targets the right people. At which point you can let them know you don't give a shit about their opinions on it at all
This is why everyone should just lie on these types of applications. If everyone lies the sheer amount of bullshit these types will have to sift through will be punishment enough
