Your definition of racism is at odds with common dictionary definitions of the word. Leftist academics have tried to redefine the word.
Again, I am not claiming that whites face racial oppression across the US. That's silly. This is whole thread only exists because of people twisting the definition of words to suit a purpose.
The same behavior is recorded in the political histories of Ancient Greece. It's nothing new. I'm just calling it out as the political trick that it is.

How does your point 1 above satisfy the "subordinates an individual" criteria for the definition of racism by the US Civil Rights Commission? It doesn't! For your point 2, to subordinate someone you need power or institutional power backing you up. If you don't have institutional power then the person you're bothering ignores you, tells others and gives you a bad reputation with people, takes you to civil court, calls the police and you are then in jail. The repercussions commensurate with your actions. I argue that your point 2 does not subordinate a white person beyond that of being attacked by an individual or small group of people because you do have recourse by law to defend yourself or have them arrested. The same with any physical assault. The significance of racism is when the person may not have recourse to defend themselves or protection by the law because of racial bias then they are put in a position of subordination and controlled.
Since 1933, the definition of racism according to Merriam-Webster has been "a belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race."
Why the more recent trend of redefining a clear term to include results of racism when institutionalized by those in power? That seems disingenuous and counterproductive.

How is a white person subordinated and controlled in the U.S. based on race to where that white person does not have recourse to the the law, the courts, the police, them finding another job, or just avoiding the offending person? If you have a problem with a person you avoid them or address the law. Racially oppressed people don't escape the situation so easily hence why racism is debilitating.
Anyone who mistreats someone because of the color of their skin or defends the practice is doing wrong and I see no value in defending that. Standing against individual racism is a necessary part of standing against institutional racism and I don't think a reasonable person can condemn one but not the other.
The newspapers are not going to report on a street riot if I go out by myself on the street and break windows and set fires. To report me as a street rioter there should be a street riot which makes me part of a group dynamic. Racism is a group dynamic effort to oppress another racial group. If someone is not a street rioter without a group dynamic of street rioting how can someone be racist without a group dynamic of racism to oppress another racial group. To have a group dynamic of racism to oppress another racial group you need power.
Your down votes are proof that it is not and that we must judge people not by the color of their skin, but the content of their character, as a wiser man than me once said.
"Is any action or attitude, conscious or unconscious, that subordinates an individual or group based on skin colour or race. It can be enacted individually or institutionally."
In case you think I'm making a non sequitur again, the power component comes from the word "subordinates."
