Final answer:
Coach Yoast's attitude is inconsistent as he promotes team unity and safety, but this contradicts the idea of accountable action against social injustice by preventing his players from joining a social movement.
Step-by-step explanation:
The inconsistency in Coach Yoast's attitude may arise from the fact that he promotes a message of unity and collaboration within the team, yet this is contrasted by an act that could appear as him preventing his players from being a part of a significant social movement which is about facing issues of discrimination and injustice.
This presents a paradox as stopping the students could be seen as silencing their voices, even if it is intended to keep them safe and prevent them from engaging in potentially harmful situations, like a riot.
Thus, Coach Yoast's attitude may align with fostering team unity and ensuring the safety of his players, but it contradicts the civic responsibility and the accountable action that comes with standing against social injustice.
