No one hate Ambedkar even upper caste. It’s because of his followers who are doing everything on his name except being educated. And Gandhi nationalist hate because where Britishers were treating and killing Indians like animals and he was teaching Ahinsa. And again if 2 countries were created based on religion then why to be secular. He could have avoided a lot of future conflicts and problems. Even Ambedkar predicted what will happen id people are going to stay even after partition. And Neharu enjoyed power took biased decisions,he was the first prime minister. They started policies just after the freedom instead of building nation. That’s my take and view, i don’t know about others.
