Final answer:
Outmoded customs should be abolished because they hinder social progress, promote discrimination, discourage innovation, and violate human rights.
Step-by-step explanation:
There are four reasons why outmoded customs should be abolished. Firstly, they hinder social progress by upholding outdated practices that no longer serve societal needs or reflect current values. Secondly, outmoded customs may promote discrimination by perpetuating inequities and biases based on race, gender, sexual orientation, and other characteristics. Thirdly, such customs can discourage innovation by resisting new ideas and technologies that are essential for societal advancement.
Lastly, they might violate human rights, by imposing restrictions and practices that harm individuals or deny them their fundamental freedoms. For instance, segregation in schools was once a norm, but it impeded societal development until deemed unconstitutional in Brown v. Board of Education (1954). Similarly, social policies like abortion rights, gun ownership, and the rights of LGBTQ individuals have been contentious due to conflicting opinions shaped by traditional beliefs.
