What is wrong being yourself?
If you find a reality that is an upfront to polite society and you find that you can make a living out of it, then it is not a bad thing. Nor is it a wrong thing.
Of course, polite society will say you are being caustic, acidic, sharp tongue, abrasive, etc.
But there is another section of society who is with you. And if you are popular with the general public - and as a result, you are successful - then that is really not a bad thing.
The truth is that it is really hard to be really nice and popular with everybody. There are people who are jealous and hate to see you do well. There is no need to obtain general acceptance.
I am probably spending too much time with people who want you to endear to them. There is so much hypocrisy when people pretend to be nice but in reality hate your guts. There is so much pretense that you do not know the reality.
Equally, I would probably not want to live in an environment where everybody shouts at you in your face all the time, and wish you ill or death.
The bottomline is the ultimate intention of the person. If you know that the person is ultimately kind, may not be nice, doesn't really mean the words used, but merely describing things the way she sees it without mincing words, and to be brutally honest, then I suppose one would not take offense, if the blunt words are not directed at you or are directed at someone else.
It is really a fine line. And only a master can walk that fine line and not fall.
Not everybody likes the jokes by Joan Rivers, but she was a master that brute honesty.
