What was a common viewpoint of those opposed to American imperialism in the late 19th century?

During the late 19th century, many individuals who opposed American imperialism articulated the belief that it was un-American to impose values on other countries. This perspective was rooted in the nation's founding principles, which emphasized self-determination and the idea that each country should have the right to govern itself and develop its own societal norms without external interference. Critics of imperialism argued that forcibly instilling American values and systems onto other nations contradicted the very ideals of liberty and independence that the United States professed to stand for. This viewpoint reflected a broader sentiment that the U.S. should act as a champion of freedom rather than as an oppressor, highlighting ethical and moral considerations in the debate over imperial expansion.

The other viewpoints provided lack the foundational ethos that the anti-imperialist argument emphasized. For instance, the notion that imperialism would enhance trade or prevent military conflicts does not address the ethical implications of imposing control over other nations. Similarly, the promotion of democracy, while a common justification for imperialist actions by proponents, was seen by critics as a façade for economic and territorial gain rather than a genuine effort to uplift other societies.
