I'm a HCP so deal with many different (we're not supposed to call them "Patients" they are "Service Users" )
They will use a whole raft of ways to decribe themselves.
But terms like EMI (Elderly Mentally Impaired) aren't used (now more commonly Dementia Unit)
My patients will 99% say "I;m a diabetic/I'm diabetic " not "I have diabetes"
And , this'll sting, but I have a patient who refers to himself as "a cripple". His words.
"Are you taking any new medication Mr X"
"No, and I'm still a cripple"
Am I supposed to be offended on his behalf and say "Oh, we don't use words like that Mr X"
Yes, there is a lot of terminology that isn't used now. And yes there will still be patients (oh, service users ) who say "He's an Asian Dr but he's very nice" . They think it's a backhanded compliment.
Some are hideously racist/sexist/homophobic/Islamaphobic /xenophobic/ any other phobic or ~ist.
But I am not going to be offended on their behalf. That is patronisig to the extreme.
