When you go outside in this world and you are polite you will start to see somebody is always being a jerk, somebody is disrespectful, somebody does not take life seriously at all, and only then when we go into the workplace where the same idiots who are disrespectful before the job are now your boss, co-workers, who hides this fact JUST TO KEEP THEIR JOB.
Other times you are used and you do not know your rights and their fore your unable to actually function. Like somebody might not want you because your race, your gender/sex, your happy upbeat attitude, or the fact your so clean your not going to buy drugs from them or know their kind of beat.
The reality people get income and work and shut their mouths momentarily. They will attempt to discriminate and take advantage of you, making you do tasks that has to do with nothing at all. The reality when you go to work and your input is not worth anything and they expect you to behave like a robot.
Beyond that where does it hit ?
Remember when you was a kid and you was behaved or misbehaved at a school or home. You can never do it at both places. So sometimes people misbehave at work ( but of course they need the money ) and other times they misbehave at home ( called a domestic dispute where the police comes in, lawyers, court room cases ), but again sometimes people go to a bar, or lounge, get drunk, maybe take in a lap-dance or see magic-mike and sing some songs at the karoke bar or arcade. Then comes home and be happy, or go to work and feel a bit okay. Sometimes people have addictions, drugs, booze, or something else.
The reality is this.
Somebody does something.
You watch too much movies.
It starts to add up and you make an opinion.
Racism begins in the workplace, the school-yard, and maybe somewhere in between.
Their are no bad races.
Just people who misbehaves.
