What are the benefits and dangers of always being politically correct?

Can someone please explain to me the benefits of always using politically correct terminology, even when the terminology itself disguises the ugliness of actions and behavoirs and the negative effects it can have on the person it refers to or the society surrounding it?

I say this from the point of view who has been exposed to many ugly things and was ugly and had the potential to become much uglier. Far from perfect though I still am.

It is not that I don’t have empathy. I just see the value of acknowledging things. An addict must first acknowledge s/he has a problem. In my experience this is applies to any change one must identify what they want to change and have motivation to try. If the world and people are too afraid or too polite to make candid statements a person will could potentially never acknowledge the things s/he is and the damage it is doing to the person and the larger group.

Admittedly other people can’t force people out of denial but acting as if there behavior is not a problem or not acknowledging their behavior or identifying it as negative is that not the behavior of a codependent?

I found I personally have benefited when people cut through the bullshit and when I was honest with myself. In fact I am thankful for it.

I am not advocating cruelty but honesty. I endeavor to support someone when they are making a true effort. I do put limitations and am cautious, I know I run the risk of being co dependent again. I don’t know if I have helped anyone in a real way but I have tried. And I treat people with compassion. I know I have hurt and been hurt by honesty. But it was a healing hurt rather then rip the hole open wider and grind some bacteria in.

So can someone tell me what the logic is of politically correctness?

I am not talking about equality or human rights issues. A few examples: white trash, rabid fundamentalists, crazy people: defined as people with unspecified problems that cause them to sabotage themselves and others without seriously trying to get help, freeloaders and deadbeats, users, methheads, alcoholics, there are more but that gives you the jist.

I recognize I have an unpopular opinion. Feel free to point out errors in my position or have a discussion amongst yourselves but please remember to be respectful of each other.
