Argumentum ad baculum
Argumentum ad baculum (Latin for "argument to the cudgel" or "appeal to the stick") is a type of argument made when one attempts to appeal to force to bring about the acceptance of a conclusion. One participates in argumentum ad baculum when one emphasizes the negative consequences of holding the contrary position, regardless of the contrary position's truth value—particularly when the argument-maker himself causes (or threatens to cause) those negative consequences.
