I know I have been guilty of generalisations, elegran, it's laziness really and only looks at people on a very superficial level. I also know that I shouldn't judge a book by its cover, yet continually have to pull myself up for doing precisely that, so have to ask myself, is that because I have learnt that certain types of people won't have anything in common with me in the past? Or is it a natural instinct for self-preservation?
Yes, I do know exactly what you mean by terms. A friend of mine with ME is incensed by the term 'invalid'. As she says, Invalid means not fit for purpose.
