Believe me, the racism you experience is VERY different from the racism experienced by all minorities, whether URM or ORM. The racism experienced by minorities is many times institutional racism. Whites rarely, if ever, experience this. Study after study has shown that many minorities, especially blacks, until today face discrimination in the workplace, in universities, basically in the entire society. Obama's election does not mean America is post-racial - in fact, some studies show that it has increased racist tendencies among many Americans.
Minorities are also stereotyped much more.. blacks are criminals, hispanics are illegal immigrants, brown people are terrorists etc. etc. And these affect them in many manners. I have many "brown" friends who absolutely DREAD going thru airport security - who have their patriotism questioned every single day. Is your patriotism questioned? If you grow a beard, will people start questioning your patriotism? How many blacks have grown to hate the police because of how they are always targeted? etc etc I could give you a hundred examples of how every minority experiences some degree of racism in this country.
Yes, whites experience racism. But if you think the racism experienced by whites is the same as the racism that minorities experience today, you are wrong.
