The purpose of the equivocation fallacy is to confuse the issue at hand by using a word or phrase that has more than one meaning.
This can make it difficult for the listener to understand what the speaker is trying to say, and can lead to misunderstandings. The equivocation fallacy is often used in arguments where one person is trying to make a point that the other person does not agree with.
For example, if someone were to say "I'm not a racist, but I don't like black people," they would be using the equivocation fallacy. In this case, the word "racist" is being used to mean two different things: someone who is prejudiced against people of a certain race, and someone who simply doesn't like people of a certain race. This makes it difficult to understand what the speaker is trying to say, and can lead to misunderstandings.
