Nonviolence can be used in many circumstances as an effective tactic, but it is irrelevant, irresponsible, and utterly ridiculous to even consider it as a strategy. So yes, nonviolence should be utilized as a tactic where pertinent, and in turn pacifism, as an ideology and a strategy, must be purged from our movement.
Radicals around me from the far-Left, mainly anarchists, Marxists, and non-affiliated anti-fascists, since Obama was elected, have been up in arms about the looming potential of maybe losing their arms. After another example of mass death via the easy accessibility of mass-murdering weapons, Democratic politicians in the US are trying again to reform the legalize-faire laws on guns. People I know are saying guns=revolution, that they, as a small minority in arms, will have the ability to stop the neoliberal-State and/or fascist-State.
