Is he fat? No he is "horizontally challenged"

Are you always Politically Correct in what you say? Meaning do you refer a bum as a 'displaced homeowner' or a blind person as a 'visually challenged' person? Or am I the only one who mostly calls a spade a spade?

"Politically Correct"
According to wiki (well they have referenced it to a book so it's not the work of a 12 year old kid):
Political correctness is a term which denotes language, ideas, policies, and behavior seen as seeking to minimize social and institutional offense in occupational, gender, racial, cultural, sexual orientation, handicap, and age-related contexts. In current usage, the terms are often used to connote intolerance, while the usage politically incorrect has been used by some as an implicitly positive self-description.

Some examples
Say no to fat, say yes to "horizontally challenged"
Say no to thin, say yes to "horizontally challenged"

Say no to tall, say yes to "vertically challenged"
Say no to short, say yes to "vertically challenged"
Say no to midget, say yes to "vertically challenged"

In the US, say no to black, say yes to "African American"
In the US, say no white, say yes to "Caucasian"
In the US, say no to Indian, say yes to "native American"
In the UK, say no to Paki, say yes to "Pakistani"

I don't know how correct they are but a list of "politically correct" words can be found here. A book that is quite good is The Official Politically Correct Dictionary.

Nobody likes racism
I see the point in many cases. Racism exists and racism is a disease. In the UK, the word 'Paki' has been misused so much so that you can't call a Paki a Paki anymore. This Prince whatever got into quite a mess for using this 'Paki' word. And it makes sense.

The funny thing is when Indians or Bengalis get called 'Pakis' by the Caucasians (trying to be politically correct here!). If one knows it, the Southern part of India (Tamil Nadu, etc) and Srilanka demographically have darker skin colour than the northern part of India, Pakistan, Afghanistan, etc. When a Tamil gets called a Paki (and it happened to my Tamil colleague), it gets strangely hilarious. It's like calling Caucasian Brits as Polish!
Imagine a White bloke saying to a South Indian "Go home, Paki" to which the South Indian replies "Get lost, you Polish freak". Nah, my South Indian colleague wasn't like this when he got called a Paki, but I have this phrase in my mind just in case I get called 'Paki' by a Caucasian Brit!

Similarly, everyone knows well the sensitivity regarding the word 'black' and 'nigger'. There's a lot of politically correct words these days to replace such words.

Nobody likes mockery
Racism is the most common issue that initiated so many politically correct words today. However, people can get offended without having to resort to any racial terms.

Take 'fat' for example. A lot of fat kids in school are subject to bullying and harrassment due to the fact that they are overweight or sometimes obese. Now obesity can be a medical condition; it's not always down to eating shit loads of junk food. And grown-up fat people also get victimised by the 'physically fit' people regularly. Hence the politically correct word 'horizontally challenged'.

Similarly, midgets are to be called "vertically challenged", a ghetto area/neighbourhood is to be called "economically disadvantaged area".

Excuse my mind for thinking about this particular conversation -
Person A: You live in a ghetto!
Person B: No you twat, I live in an economically disadvantaged area.

Nobody likes insults
Sister term for mockery really. A bum might feel insulted if you call him a bum, so call him a "homeless person". And don't call a lunatic a lunatic! Before you know it, he might turn you into a "physically challenged" person. Mentally ill is the politically correct word for a crazy person.

And there are many cultural terms as well, that are sometimes grouped into racial insults but they are usually used by people to refer to a person from their own race that they see as not 'culturally fit'. 'Fresh-off-the-boat (or FOB)' is one such word used in America to imply any immigrant and 'Freshie' is the corresponding word in England. The ironic thing is when third-generation immigrants use these words to new immigrants (or first-generation immigrants) that come in the land of opportunity for the same reason as their own forefathers. Try calling your dad a FOB and your mum a freshie next time!

"I'm not racist, I just don't like white people!"
Haha that's a good one. I know some "Desi" people (South Asians) have this mentality and so do some black people. It is okay for an Indian to vote nobody but an Indian, or a black to vote for nobody but Obama, but it ain't okay for a white to vote a white!

You're just as racist as a white person who insults non-whites if you are a non-white person insulting a white.
