Well - some years ago now we were all requested to call people with diabetes exactly that hence using the phrase PWD in full every time you wished to convey summat like Blimey - every diabetic in Timbuktu has been issued with HCL technology! or anything really - whereas I can't usually be arsed to type or say more words than are necessary to convey my message. If I refer to you, or Patti, Northerner or someone as eg examples of UK diabetics I happen to have met - how on earth is that inferring that diabetic describes anything about each of you other than the fact we all have diabetes and as it happens, all use insulin to treat it. There is no way whatever that anyone could possibly glean any other morsel of info about us, from that word - and I deliberately chose those individuals because we really don't have very much else in common, really!
(and also of course because I've met a limited number of people from forums generally 😉 )
I remember a GP explaining summat medical to me one day about 15 years ago about my thyroid TSH level that contained the phrase 'people like you blah dee blah..' and I responded with the query 'Now doc, when you say 'people like you' do you mean "female, brunette recently retired corporate international insurance brokers", or perchance "people with diabetes" then?' Broad grin from Doc and the firm response, 'The latter!'
