That's fine if you want to see it argued in court, but I'm pretty sure the institutionalized and systemic nature if racism makes the difference very distinct, in short racism is prejudice, prejudice isn't necessarily racism. And while prejudging is never the best course of action, it is sometimes understandable, as in the case of a young black man growing up in Tennessee in the 60's, prejudging could be the difference between being lynched or not, and it's hard to shake those prejudices.
