Gandhi on the Currency

By printing Gandhi on currency notes we are insulting the great old man. And we appear to be hypocritical; we display Gandhi so much and practise nothing of what he stood for. Lately, we have added a reproduction of his round-frame spectacles on the same currency notes. What do they symbolize except short-sightedness? What is there to be proud of that deficiency? India has innumerable heroes, ancient, medieval and modern. Why not deploy a separate example with each denomination?
