From FOREVER PEOPLE 3, July 1971. The spectre of Nazism in Kirby's Fourth World series, portrayed as Anti-Life (i.e., sacrificing your life and personal identity to an ideological cause, and justifying any violence by your cause as a necessary means toward achieving that cause, as an army of anonymous masked "Justifiers").
A perfect commentary in the current era on Antifa or Black Lives Matter movements.
Snopes' interpretation of this is ironic, to say the least.
