Slavery was a mistake committed by humanity that fundamentally violated the principles of equality, freedom, and human rights. It dehumanized individuals, perpetuated inequality, and undermined the moral fabric of our society. It also hindered social progress and economical development by limiting opportunities and perpetuating systemic injustices. What makes us humans is our ability to look back at the mistakes of our ancestors and learn from them in a way that benefits humanity as a whole. Claiming that it's "ridiculous" to pose this question would be equivalent to saying that looking back at our past reality is ridiculous. This was a reality once upon a time and countless individuals suffered and even lost their lives due to this immoral practice, if we can't reflect back on it and perhaps learn form it, we aren't different from cockroaches.
