How blind children learn the verb 'see'

I am inclined to agree that the title would be improved if it ended with a question mark. I suspect that the point of this article as written, was to generate intelligent speculation as to how blind children responded to the statements they were asked, thus challenging the participants in this forum to deeply reflect upon that which was offered. In point of fact, the absence of the researchers "conclusions", as to said behavior of the blind children, compelled me to think deeply and try to reason out what was actually occurring. This seems fair, and perhaps the purpose of this forum. What confuses and bothers me is the lack of constructive criticism herein. This is a science forum, therefore it make perfect sense to frame criticism with scientific discipline and reasoning. Lets assume, for the sake of discussion, that the writer erred, actually, or in terms of someones perception, in the writing of their article. Does that justify the ugly language and thoughtless comments in this blog? Why participate in a science forum if you lack the discipline to evaluate the information that is offered? Such angry responses say nothing about science, but do indicate the limits and poor attitudes of some of the participants. I came to this forum hoping for enlightened dialog and fair play. It is probable that those who have chosen to criticize this article, in the worst terms, will be unreceptive to the need for common decency, and enlightened self-interest. Their example is a clear indication of a dumbed down society.
