Extended Analogy

This fallacy is committed when, while arguing a general rule, one makes a comparison between a single aspect of two situations, and a reply treats it as a claim that the two are directly analogous to each other. For example

"I do not support the use of [software] cracks to bypass copy protection, regardless of my opposition to copy protection. I believe it is always wrong to oppose the law by breaking it."
"Such a position is odious: It implies that you would not have supported Martin Luther King Jr."
"Are you saying that software piracy is as important as the struggle for Black liberation? How dare you!"

(Also an example of Appeal to Worse Problems)
