I do not wish to give any comments on the contents of the letter of Mr/Ms Anonymous as he/she chooses to enter into discussion remaining invisible. A person with some ideas ,if he/she wants to contribute for a cause should come out in the open as many have done in your blog and participate in the blog instead of shooting comments incognito.
I suggest that you may adopt an editorial policy to publish matter contributed only by writers who identify themselves and not by those who prefer to write whatever they want by remaining anonymous. Any matter received from an anonymous writer only means that the writer does not want to take responsibility for what he/she writes.
Even reputed newspapers make it clear that those who wants their letters to be published should write their name and address.
With kind regards,
