Which term best describes the action of using force or strong arguments to gain a point?

The term "bludgeon" is the most fitting description for using force or strong arguments to gain a point. In a metaphorical sense, to bludgeon someone in a debate or argument means to overpower them through aggressive tactics or overwhelming evidence, akin to the physical act of striking someone with a heavy object. This conveys a sense of coercion or intimidation rather than a balanced dialogue.

The other terms do not align with the concept of using forceful arguments. "Cauterize" refers to the process of burning a part of the body to stop bleeding or prevent infection, which is unrelated to argumentation or persuasion. "Cancellation" implies the annulment or voiding of something, which does not relate to gaining a point in a discussion. "Chauvinism" denotes an excessive or prejudiced loyalty to one's own group, often at the expense of others, and does not pertain to the method of arguing or persuading effectively. Thus, "bludgeon" clearly stands out as the appropriate term for the action described.
