similiar thing happened to me
when a blind man was near whining
he was just lost at the bus station

many around, few smiled at him, making jokes, many already observed him as he bounced on the fencing there

1 second and my body was hurling toward him, no questions, i got it all, even his face was talking: help!

no other made a move!

he was lost as i expected, can not find the bus to his home, i searched the right one and stayed with him till it arrived and all of them, waiting for the bus were waiting till i let them.. after him to borad the bus.. he was smiling and holding my hands in joy, as if he was trying to see into my eyes, he "looked" as if he can see.. this was the best reward for me

people have their speed of allowance, learning and forgeting
many predjudices, many false associations

so i undesrstand your worries
but i see it as inevitable for their own growth
where they do not made their part, they will get more of these situations on other occasions, graduating in manifestation, till they will end partially or fully disabled to see/grasp more!

..that, for wehat they have come here in the first place!
