It seems to me there is much too much information missing to make an informed choice about this.

I use a walker and every time I go anywhere there is at least one annoying or infuriating or just plain dangerous occurrence; I'm not surprised it has come to this. And it won't solve anything. Sooner or later they'll have come to the same table and work together to make Sing Out! accessible to visually impaired people.

Exactly how will negative behaviour help to create a positive result?
