And I’m thinking, maybe they marched all the kids in, and the photographer arranged them all by height, and then when they were ready, they said “Oh, and don’t forget the kid in the wheelchair.”
The kid looks happy enough, like he knows this is how his life is. He’s in a wheelchair that is quite big, so nobody is ever really up against him. They probably walk pretty far away so they don’t get run over.
And I guess either he’s in the front of the room, or they made a wide walkway for him to pull into. At an auditorium, he’ll stick out in an aisle, and if he’s lucky it’s a modern one where a couple people can sit in chairs that are close enough he can yell to them, while everybody else complains that the wheelchair is sticking into the aisle, and people behind him can’t see because his head is 2 feet higher than all the others.
Neither you or I were there, so we don't really know what happened. I'm willing to give the photographer the benefit of the doubt that the picture was taken without any malice or intent of hurting this child or his family's feelings.
Others may choose to read into this picture something that may -- or may not -- be there. I really don't think any reasonable, decent human being would've knowingly positioned all the kids this way indicating separation between the physically challenged child and the others.
Some people look for reasons and opportunities to be offended when no offense or malice was ever intended. I'm not one of those people.
