During the 1990s, Congress prohibited private businesses from discriminating in employment, public services, and public accommodations on the basis of physical or mental disabilities. This act creates a clash between:

Freedom and equality.

Explanation:

The Congress during the 1990's enacted "The Civil Rights Act" on July 2, 1964 which prohibited private bisinesses unequal application of discrimination and racial segregation in employment, public services, and public accomodations, on the bases of physical and mental disabilities, which clashes between the freedom and equality of the citizens.

The Act further prohibits unequal application of Voter registration requirements, and racial segregation in schools, employment, and public accomodations and also on bases of mental and physical disabilities.
