How could Rousseau’s concept of "general will" be used to eliminate the rights of the minority?  

The Concept of General Will focuses on the common good or common interest. And the Minority is something which are lower in number. A Common good or Common interest will always tilt towards the interest of Majority. Hence, the Concept of General Will of Rousseau will eliminate the right of the minority.

General Will: The general will is central to the political philosophy of Jean-Jacques Rousseau and an important concept in modern republican thought. In Du Contrat social (1762; The Social Contract), Rousseau argued that freedom and authority are not contradictory, since legitimate laws are founded on the general will of the citizens. In obeying the law, the individual citizen is thus only obeying himself as a member of the political community.

The Critiques of this concept suggest that it neglects the rights and interest of minority, since it only focuses on general will and neglects the Rights of An Individual.

Rousseau's concept of "general will" could be used to eliminate minority rights if it is proven that minority rights do not match or violate the wishes of the majority of the population.

Explanation:

According to Rousseau, the "general will" is the term that refers to the obligation of governments to meet the general will of the people, represented by the will of the majority of citizens.

This term reaffirms the sovereignty that the people have in the face of the governmental forms of the country, showing that the entire political system and the region must be submissive to the wishes and objectives that the people express in general. Despite being a highly important term for maintaining democracy, "general will" can be used to limit, or even eliminate, the rights achieved by social minorities. This is because this term can be used to show that the rights of social minorities hurt the wishes of the majority of the population and therefore must be eliminated.
