The big difference here is that 'white' was always just 'white' whereas 'black' was not just a colour but also a metaphor for stuipid, lazy, uneducated, slave, criminal, less worthy, less than human etc.
I am german living in South Africa and while being called white was never discriminatory, the term black was and is almost always meant in a derogatory fashion.
you need to understand that because of past injustices and discrimination the term black is more than just a colour description.
As much as i don't agree with a lot of the PC excesses, sometimes it is prudent to think about the history behind the need to be more sensitive.
Ah. This would be because of cultural differences between you and I in this case. I can understand that the past meanings of the word "black" could be interpreted in a derogatory fashion, however from what I understand of my culture and experiences, the word itself is just used to describe the colour of the person's skin itself.
With words like these, I take them at their literal point, rather than their word associations as I find it makes the world and the language a simplier place.
To chime in with the hearing loss and the visual loss stuff, I am profoundly deaf but I often have to say that I have a hearing loss or hard of hearing, rather than saying that I am profoundly deaf. Reason is, as soon as you say the word "deaf" itself, people automatically think of the signing community. Thing is, I ain't part of that. Never will. I talk as well as most people and communicate effectively through speech and is degree educated. Additionally, I have a Cochlea Implant. Now, the tricky thing is, if I did not have the Cochlea Implant itself, the sound needs to be above 100dB for me to naturally hear anything. So in all intents and purposes, I am practically as deaf as a doorpost. But with the Cochlea Implant itself, the quietest is around about 30dB. Or thereabouts. Maybe less, as I've not been tested for a while... So most of the time, I am just slightly hard of hearing with it. Other times that I don't use it (sleeping!) I'm completely incapable of hearing normal conversations at all (which is wonderful for sleeping!).
With the PC stuff....it sometimes can be like walking through a room that is forever hazy with possibly meanings of the words used, but never clear-cut. Its very annoying as you do not generally get an idea what is actually meant by the original speaker.
