Men, Women . . . and Other?

 

This is the sign for the elevator at the Torpedo Factory in Alexandria, VA. When I first saw it I was impressed by a sign that actually showed someone in a wheelchair using the elevator. Afterall, those who are bound to a wheelchair are those who need an elevator, right? If you can walk you have the luxury of using the stairs. So it has always seemed silly to me to have a sign showing two able bodied people riding in the elevator.

Then I looked again and wondered, "Does this sign segregate?" Does it make the person in a wheelchair niether male nor female, just an 'other'?
