Yes, quote the guy who brought in caste-based reservation in India. Quote the guy who wanted a separate electorate for Dalits and other religious communities. Quote the guy who did not understand Gandhi !
Now there is 49.5% reservation now in educational institutions in India, yes 49.5% !!, because that's the highest allowed by the constitution, otherwise they would have gone higher. It's something similar to "affirmative action" in the US, but totally taken over by politicians to play electoral politics, to pump in the votes from the lower sections of society.
Gandhi had the vision to understand that caste-based reservations would lead to caste-based politics and further affirmation of casteism in India, Ambedkar never could fathom that, or maybe he could and ignored it!
Anyway, please don't quote someone who didn't understand the ideas or vision of Gandhi, please don't.
