There may be advantages of having sight, but I'm content as a person.
I'm not against sight, but as for me, I don't want it, because I'm already
independent.
The NFB's philosophy is that blind people are able to do whatever we put our
minds to.
It's that simple!
We don't want pity, and we don't want to be a charity case for the state!
We want equality, and if given that equality, we can do whatever the sighted
people do!
Catching a ball?
There are beep ball teams already established.
Good grief!
Blessings, Joshua

Something doesn't make sense about this though.  How can you say you're
happy being blind unless who you are is a blind person. Vision is a very
handy thing. With vision you can catch a ball or run the high hurdles. You
can appreciate a photograph of your kids. You can fly a plane or drive a
taxi. Why wouldn't you want to be able to do those things?

If you're blind, there are a lot of things you can't do. But to me, that has
nothing more to do with who I am than does not being able to do math like
Albert Einstein or throw a football like Peyton Manning. That has nothing to
do with who I am. I'm just not a blind guy.
Would I like to be able to do math like Albert Einstein or throw a football
like Peyton Manning? Sure. Would I like to be able to see like everybody
else? You bet.
