Is there a specific label or name for the rhetorical tool of using a little bit of truth to try and disprove another claim. For example, if Person A says something like "philanthropy is less effective as a means to maximize well-being than if we just taxed everyone more" and in response Person B says "but philanthropy does some good". Even assuming Person B's response is truthful, it seems they are avoiding addressing the true question. I know this is similar to a red herring fallacy, but I was wondering if there is a more precise name (or set of work) looking at the use of a nugget of truth to try and distract from or disprove a larger issue. Thank you.
