The argument made by Thurgood Marshall that helped shape the Brown v. Board was that separate facilities were unequal and made African American children feel inferior.

The rule 'separate but equal' did not apply to public education because African American students felt inferior and in that case, separation did not give them such opportunities like to white children; therefore, there were no equal chances.On December 8, 1953, Thurgood Marshall, the chief legal counsel of the National Association for the Advancement of Colored People (NAACP) gave the argument for the plaintiffs saying "with education, this Court has made segregation and equivalent inequality concepts. They have equal rating, equal footing, and if segregation thus necessarily imports inequality, it makes no great difference whether we say that the Negro is wronged because he is segregated, or that he is wronged because he received unequal treatment.."
