Why did Madison believe that a pure democracy was not suitable as a model for a government of US?

James Madison believed that a pure democracy was unsuitable for the United States because it could lead to the tyranny of the majority, where the rights and interests of minority groups could be oppressed. He argued that direct democracy might result in impulsive decisions driven by passions rather than reasoned deliberation. Instead, Madison advocated for a republican form of government, where representatives would be elected to make informed decisions, thereby protecting individual rights and promoting stability. This structure would help balance the will of the majority with the need to safeguard minority rights and ensure a more deliberative governance process.
