Definition

An argumentum ad baculum is a logical argument that, rather than prove or present evidence for a claim, threatens any who dare argue with the person or group making the claim.

The presence of such a threat is often a good reason to avoid stating an opposing view, but manifestly does not support the truth or falsity of the claim under consideration.

Example

"Questioning the validity of my proofs is likely to get you a permanent ban."

Also known as

This is also called an appeal to force.
