A discussion stopper, also known as a debate stopper or a thought-terminating cliché, refers to a phrase or statement used to halt a conversation or debate without addressing the underlying issues. These phrases can be powerful tools for shutting down discussions, as they create an illusion of resolution without actually resolving the disagreement.
An invalid argument, on the other hand, refers to a line of reasoning that is flawed or illogical. Invalid arguments may be intentionally deceptive or may simply be the result of faulty reasoning. Common types of invalid arguments include ad hominem attacks, circular reasoning, and appeals to emotion.
A thought-terminating cliché can also be an example of an invalid argument if it is used to deflect attention away from a legitimate point of discussion or to avoid addressing an uncomfortable truth. For example, saying “that’s just the way things are” can be a thought-terminating cliché that is used to shut down a conversation about systemic injustice.
Overall, a discussion stopper or thought-terminating cliché is not a valid or constructive way to engage in a conversation or debate, as it does not address the underlying issues or allow for meaningful dialogue.
