Statist claim: Democracy excuses aggression.

Fallacy:

Statist: A recent poll has 55% of the public supporting stricter gun control laws, with 44% opposed.

(Implication: the threat or initiation of violence against peaceful people is justified by numbers.)

Response:

Democracy? I want nothing to do with a system which operates on the premise that my rights don't exist simply because I am outnumbered. — R. Lee Wrights

The threat or initiation of violence (violation of the Non-Aggression Principle) does not suddenly become moral because you outnumber a group (even if you go through a rat's nest of "representatives" and claim you're a "republic" rather than a "democracy").

It does not become moral just because said majority hires people, dresses them in uniforms, and pays them (with stolen money) to initiate violence; special pleading is a fallacy, and evil actions do not become good because a gang calling itself "the state" demands them. (DBR)

Of the political superstitions lately alluded to, none is so universally diffused as the notion that majorities are omnipotent. Under the impression that the preservation of order will ever require power to be wielded by some party, the moral sense of our time feels that such power cannot rightly be conferred on any but the largest moiety of society. It interprets literally the saying that "the voice of the people is the voice of God," and, transferring to the one the sacredness attached to the other, it concludes that from the will of the people - that is, of the majority - there can be no appeal. Yet is this belief entirely erroneous. - Herbert Spencer, The Right to Ignore the State
