Political correctness

Lets talk a little PC
If you are a middle class man and you pay a woman for sex, she is called a whore(among other things) and it is called a sin.
If you are wealthy and do the same thing, she is called a mistress and it is called an indiscretion.
How much sugarcoating can you put on it?


If a person is a minority, Latino, Black, Oriental, and you belong to a group that robs, kills, and deals drugs, they are called a street gang and you are called a gang-banger.
If the person who is white belongs to the same kind of group, they are called a militia and you are called a colonel. Why is this?
