Has racism been truly eliminated as claimed by many today?
Racism has been eliminated from the system i.e. the Government, Laws etc. I can say this as the laws, constitution and courts treat every citizen the same. A separate constitution is not written for Citizens based on their skin colour. If you go a few decades back this was not true, citizens were treated on the basis of their skin colour. Since the change of public opinion, equal rights have been given every citizen. Thus making the Government systems completely racism free.
Most of the society has changed and adopted people of all races but some people still consider themselves to be the superior race. Thus in the mind of such people racism still exists even though their thoughts and actions are not supported by the system they live in. In a few generations the number of such people will eventually become zero thus eliminating racism completely.
