Babasaheb Dr B.R Ambedkar

No one can hope to make any effective mark upon his time
and bring the aid that is worth bringing to great principles and
struggling causes if he is not strong in his love and his hatred. I
hate injustice, tyranny, pompousness and humbug, and my hatred
embraces all those who are guilty of them. I want to tell my
critics that I regard my feelings of hatred as a real force. They
are only the reflex of the love I bear for the causes I believe in.
—Dr. B. R. Ambedkar
in his Preface to
‘Ranade, Gandhi and Jinnah
