That's fine, but when you consider institutional discrimination your argument and general point loses its muster.
It's past the point of individuals.
It's not like some white man in overalls is standing on his porch screaming "niggers" anymore.
The problem is that it's so far ingrained into our society that mundane or routine decisions that seem innocuous are in reality discriminatory.
Look at crime in inner cities. (Yes, I realize that it is partially about class here, but considering minorities are clustered in low income areas, and urban inner cities are generally the most prevalent low income areas, you come to a conclusion)
If you're an 18 year old white kid in the suburbs smoking weed with your frienRAB, you're infinitely less likely to be arrested than if you are an 18 year old black kid in the inner city doing the same crime.
The reason is that the inner city is seen as a bastion of crime and degradation. Not because people in the inner city commit more crime than the rest of the world, but because they do so at a greater rate.
Many theories about this but the base stipulation is that it happens.
Police want to control crime -> Politicians define controlling crime as lowering crime statistics, or alternatively increasing arrest rates -> Police patrol the areas most likely to net them the most arrests -> urban inner city youth/residents in general get arrested more because they're targeted more.
It's simple.
If you asked a random person if policing methoRAB are racist, they'd say no, of course not. Maybe one or two individuals, but the entire department isn't racist.
That's because of the way they view racism. When you stop viewing it as the old farmer screaming "nigger," and start viewing it as an institutional phenomenon that has crawled its way into every facet of society, well, then you see how bad it really is.
