In the eye of the beholder

I was interviewing a man with learning difficulties and he told me he had to have help with some things because he was mentally handicapped.
I asked him to tell me what that meant.
He said, ‘It means people stare at you in the street and say horrible things in shops.’
It made me wonder how other groups might be defined, in terms of how they get treated by other people.
There was a blind man in the street collecting for a blind welfare charity. I guess his definition of being blind might be something along the lines of: ‘It means people think you won’t notice them walking past pretending they haven't seen you.’
Foreign visitor? ‘Means people raise their voices as though you’re deaf and think you’re stupid if you don’t understand the first time.’
Deaf? ‘Means people think you’re stupid if you don’t understand the first time.’
Christian?
Sadly, in many countries: ‘Means you get arrested on false pretexts, thrown in prison, lose your job or are evicted from your home and no lawyer will represent you.’
