This guy is a member of DSA, but every historical reference to “socialism in New Jersey” is to those who espoused Marxism-Leninism, Trotskyism. the Socialist Workers Party — all communist movements. That’s very telling.
New Jersey actually had voluntaristic communal experiments - the Fourierist Phalanx at Red Bank, the Vineland Community, Upton Sinclair’s Helicon Hall - but nowadays it’s all about politics.
Register Communists, not guns.
And it’s probably time to start a registry.
