What's do phones and people have in common? When they're disabled they're useless
I can't fathom how you can say that. Does that refer to you?
No, it doesn't.
The disabled are just as worthy as us for a full, complete, and happy life. It is not fair to them to think they are lesser just because they might be missing a limb. Would you like to be treated as a subhuman all because you were missing a finger?
