Well, then again, the word "mind map" is derogatory to the mentally challenged (retarded?)... so it's pick-and-choose mentality. I think political correctness only makes the problem worse. If you call someone vertically challenged, the people being called so will think that the callers are just being overtly polite to cover up their hate.

How is it offensive to say brainstorm? I'm sure anyone who says that doesn't mean anything by that. Typical British givernment changing a traditional and well-known fairy tale. Typical british.

Come on, political correctness is just a load af rubbish that gives the leftwingers their opportunity to block everything and everyone from saying what they do not want to hear.
We all know the left's favourite principle: "Freedom of speech is sacred, as long as you say what we want to hear and as long as you agree with our doctrines, if you son't, we kick your head in".
That is also how it used to go (and still does) in the former Soviet union and the earstern European countries under communist regimes. People having to go in exile or being executed, simply for voicing an opinion. The best one is, those regimes are the ones that refer to themselves as "democratic".
And, to come back to political correctness, these days it is political incorrect to say 'Fireman' or 'Policeman', should now be 'Firefighter' and 'Police Officer'.
Can you imagine one male police office who would be offended being referred to as 'policeman'? After all, he is a man who is in the police force, isn't he? The same goes for referring to a WPC as a 'police woman', aren't we talking about a woman in the police force here? So, what would be offensive about that?
The same for 'Fireman' and 'Firewoman', are we not referring to both genders, being a member of the Fire Brigade here?
So, I cannot see any fireman or firewoman being offended being referred to in this way, as you do not do their gender any injustice, do you?

It even gets worse when it comes to words referring to race, as with the previous (sexism), to the left wing racism only works one way.Just like, in their book, a man can only discriminate a woman, and the opposite is never true (I, among others have gone through a lot of suffering due to discrimination by a female (and feminist)boss, but obviously I did not have a leg to stand on when trying to report the matter, if the shoe had only been on the other foot...), now the same goes for race, as I said before, only whites can discriminate against other races, the opposite is of course impossible. So, in that respect, they have banned certain words too, and I understand some of them can be offensive (which is why I am not going to mention them here), but, in today's society, just try to report that a black person called you "Honky", you will be laughed out of the building, because that is of course not offensive (that is what society has become).

So, I say, 'To hell with political correctness', it is just nowaday's hypocrisy reaching a peak, and only the things which do not fit into their system is deemed politically incorrect. The same thing, why, in some places are we now to refer to a 'Christmas concert' as 'a festive concert', or why can we, in some instances not use the word 'Christmas' any more? The reason being it might upset immigrants. well, us, Christians have celebrated Christmas for 100s of years, it belongs to our culture, our religion, so why should we all of a sudden have to change that in order not to offend people who come to our country and do not want us to live our culture as we see fit? Have a think about all that, and I am sure, this discussion will continue in the not so distant future.
