Why don't all perceived minorities insult themselves the way that black people do?

I am lucky. I know lots of people and and I am the beneficiary of many wonderful relationships.
Some originated from where I grew up. Some are based on my experience in the service. Some are connections I made with my Arab girlfriend. Some just happen.

Having said all that…

The Arabs I know never call themselves “Camel Jockeys” or ” Ragheads”
The gay people I know never call themselves “Fags” or “Homos”.
The Hispanics I know (fabulous soldiers by the way) do not call themselves “Beaners” or “Greasers”.
The Jews I know (My sister is married to a Jewish guy) do not call themselves “Kikes” or “Hebes”
Occasionally, the black folks I know call each other “nigger”.
That is their business.

But…

What is that all about?
