Getting a gun permit in TN is actually rather restrictive compared to say, Iowa, where they approve them for blind people.

On one hand, the state shouldn’t block one’s civil rights because one is disabled.
On the other hand, blind gun-owner.
How can a blind person shoot a gun in a responsible way?
Don’t be simple-minded. Blind people can shoot a gun responsibly the same as anyone else: be sure of your target and what’s behind it. Yes, that’s more difficult for persons that have impaired or even no usable vision, but knowing many legally blind persons I can assure you that they are responsible firearms owners.
How?
People who aren’t blind have the same exact considerations, except they orient themselves with vision, whereas the blind use their other senses.
Edit: Also legally blind != completely blind.
Provided you have someone pointing you in the right direction and making sure that downrange is clear, there's nothing wrong with this.
Or alternatively, the same exact thing you’d do as a responsible gun owner who was not blind.
Even so I recommend getting a permit because carrying a lethal weapon is an awesome responsibility and needs to be treated with respect. The classes teach much useful knowledge.
