How did Lafayette support civil rights during his lifetime as noted in the biography, Why Not, Lafayette?

Lafayette's advocacy of civil rights extended to all people, which means that he opposed slavery. Why Not, Lafayette? barely touches on this issue, but worth noting is his discomfort at being waited on by slaves, even while visiting old friends who were slave owners. Why Not, Lafayette? emphasizes his work in France to secure permanent legal rights for the common people rather than any discomfort he felt at flaws in American law. In France, he was a heroic figure for commoners and an irritation for those who sought to rule France. If he was not in danger of being executed by one or another king, then he was in danger of being beheaded by the revolutionary leaders who were annoyed by his insistence that they rule justly and that they not execute people who disagreed with them. Lafayette was a complicated man, seen as weak by some historians for not using his fame and popularity to enforce his views militarily, as well as for his long years of mediating between different political groups while striving for a political consensus on human rights in France. In Why Not, Lafayette?, Fritz develops a portrait of a man whose public life represented not weakness but the courage to stand up for justice. Even when meeting Napoleon, Lafayette refused to be intimidated and told Napoleon exactly what he thought about Napoleon's rule.
