Answer:
A post-racial society is a society where racism has been overcome and no longer exists.
Step-by-step explanation:
Post-racial means that racism has been overcome or that overcoming is by means other than the adoption of racial politics.
The existence of a post-racial society means that race is a thing of the past, that the racial problem is being overcome through globalization, immigration, interracial marriage, legal equality. In this society it will no longer be necessary to adopt specifically anti-racist policies. The post-racial expression is used to say that society does not "see" the race more, it does not act more according to race, as if we have all become equal.
