No one has answered wether hunting should be extended to pheasants for the visiually impaired.
You continue to ignore or miss the point.
The article is not about EXTENDING hunting to anyone or anything, only to expanding the sighting options available to impaired hunters. Furthermore, if you cared to do any research, you would find that TX is not the first state to consider such a law. Similar laws have already been passed in several other states.
As far as I know, there is NO kind of hunting legally denied to the visually impaired so your question doesn't make sense.
