Why people think that someone had oku card automatically is a handicap?

Why people think that someone told has a oku card they think is a handicap person? Can't walk , can't talk, can't move arms ? 🤦🏻 Then dont allow for interview for work even giving them industrial training short course and hire them to work? Follow industrial requirements. If someone has oku card automatically rejected? Unless dont tell them you have a oku card ?

If can go to gym, can walk and can move arms. Just Stammer only and had oku card due learning disability like slow learner but dont tell them if I am oku if my body is physical fine and not a handicap?
