Gandhi's approach of a fast unto death worked when people did not have representation in Government. That is not the case since 1947. If Medha believes in her cause, let her take it to the next election or to the Supreme Court if the law is being violated. But her approach of hunger strike says her belief is more important than democracy or the Supreme Court - effectively undermines what modern India is today.
The Indian Constitution is just fine, the implementation may have flaws. Medha, if you want to fight, fight within the Constitution, but don't try to defeat the Constitution.
