Exactly thats what every sensible person wants, development, prosperity and harmony. But to keep a name or have an identity for your son or daughter(your so called future generation-future generation starts from your family)it is important to know your past, so even going forward you look back, if you dont you r not called a human. And i don't think you would be delighted if someone is throwing shit at your past and hurting your sentiments. So let us hope that GOD will give some sense to these people and concentrate on development without hurting anyones sentiments.
