I'm looking for the name of a logical fallacy in which person #1 makes a statement, and person #2 misinterprets it as a far more extreme statement, then rejects the extreme version.
Example (simple but contrived): I say that I've never visited the Grand Canyon. My opponent accuses of me of saying the Grand Canyon doesn't exist, and "proves me wrong" by showing me photographs.
Example (more realistic): I say that people with light skin and dark skin have no significant differences in brain structure, on average. My opponent accuses me of saying that "race is entirely irrelevant" and argues against this more extreme position.
I looked through Wikipedia's list of logical fallacies, and the closest I found is the straw man argument, in which the opponent argues against something the original speaker didn't say. But in my case, the opponent's argument isn't some random & irrelevant topic, but an extreme generalization of the original statement. I'm hoping there is a name for that particular illogical leap.
