Heres a question for you.
What drives hearing people to do the behavior described in the op to someone they know is Deaf or very hard of hearing?
You do not have to hold to a philosophical dogma and be able to articulate it well to Actually act in ways that suit or a particular dogma wishes.
How many racists really could articulate well the political or social dogmas in any racist ideology or system defined?
I argue few.
Yet racism is still on an individual level rampant.
These people dont have to even know what adusim means to act in audist ways.
So ill ask again for the sake of clarity
Why do you think the people describe dint he op would act like this? not to some stranger but to a man they are assumed to have once loved or still do
Take a shot
ill wait
