It depends on if we claim ALL US citizens are racist or not.   

You don't doubt that racism continues as  problem in this country do you?

The legal system is a part of U.S. institutions, including law enforcement and the courts.   We have hundreds if not thousands of historical examples of racism in both those institution, particularly in the south and many continue to this day.  The conservative SC just identified that race contributed to Gerrymandered proposals from a southern Republican state redistricting, that's Now.

If you mean the US ideology of a democratic society includes racism - then no.**   If you look at the actual behavior of some US institutions then you will find incidents of racism.

**It's clear that our founding document included inherent racism by not granting full citizenship to black persons.   While the law has changed, it's equally obvious that racism has not been eliminated.   

So far, we have no way to legislate what one thinks or feels.
