Racism has not been truly eliminated yet. It is true that explicit racism has been written out of our system, but after generations of differential treatment within a culture, implicit racism will still exist. To clarify, explicit racism is conscious and blatant acknowledgement of racist beliefs and implicit racism can be found in the unconscious biases that exist regardless of intent.

Everyone carries explicit and non-obvious, implicit attitudes that are a result of their culture, family values, peers, entertainment industry, etc. For the most part, it is not acceptable to be explicitly racist, so many have taken on implicit attitudes. Others have not taken into account the environmental factors in their life that could cause implicit racist attitudes, and lack the self-awareness necessary to counter latent stereotyped beliefs.

Explicit racism may come to end soon, but our culture has many more generations to heal these implicit attitudes imprinted on our communities after years of abuse.
