In a discussion about taxes and war, which rhetorical technique is used when the speaker questions the sincerity of the president's statements?

The rhetorical technique most accurately described in the scenario of questioning the sincerity of the president’s statements is disapproving a minor point. This method involves challenging a specific aspect of an argument that may appear to detract from the overall credibility or integrity of the speaker. By focusing on the president’s sincerity, the speaker aims to undermine the trustworthiness of the president's claims about taxes and war, which can lead the audience to question the integrity of the broader argument being presented. This approach can be persuasive in influencing how an audience perceives the speaker's positions, as it casts doubt on the person's commitment to truthfulness in their statements.
