You aren't being oppressed the other party doesn't want to interact with you, unless that party is government providing base services to all (e.g. police/courts/border protection).
Actually, you can be.
How?
You *are* being oppressed if mutually consensual behavior is interfered with by others including the State.
You *are* being oppressed if you are coerced into a relationship you don't want.
You are not being coerced into anything. If you don't want to serve food to Blacks, don't open a restaurant. It's your choice.
Umm, no, freedom doesn't work like that. If you open a *private* establishment, you have the right, according to the constitution, to deny *anyone* the right to enter or eat in your restraunt. However, if you were banned from using the government postal service for being Jewish, then yes, you are being oppressed.
By the way, you are also not allowed to dump toxic waste in your own backyard. Are you being oppressed?
Depends. Does it affect your neighbors? If so, then no. If not, then yes.
An employer-employee relationship is like a marriage or any other arrangement between adults -mutually consensual.
In a fantasy world, it is mutually consensual. It the real world, it is seldom mutual.
Tough shit. If you don't like your job, no one's forcing you to stay. Just leave it and get another one.
