Statist claim: We must have moderation.

Fallacy:

"So, there really is no good answer. America has always been a mix of democracy, capitalism and socialism … personally, I like the blend, because I believe in moderation." (Clare King)

Response:

Tu ne cede malis, sed contra audentior ito. - motto of the Ludwig von Mises Institute

["Do not give in to evil but proceed ever more boldly against it."]

Urge immediate abolition as earnestly as we may, it will alas! be gradual abolition in the end. We have never said that slavery would be overthrown by a single blow; that it ought to be we shall always contend. — William Lloyd Garrison

There are areas in which compromise is good, and areas where it isn't. Freedom isn't one where one should compromise. Certainly, accept any gradual improvement (but not in exchange for a greater loss, or for harm to some); but the goal is a free society, not a less-evil state.

"Moderation" I believe is some degree of initiation of violence against peaceful people. Keep some of the cancer. Some of the poison. Because I'm a "moderate".

I'm not a racist, but I like to call some black people racist names. Because I'm a moderate.

Clearly we don't accept moderation in these things. It is not a value in itself, but only in context—and it is great evil in the context of individual liberties. (DBR)

Gradualism in theory is perpetuity in practice. - William Lloyd Garrison
