Tagore's political views were complicated. He criticized European colonialism and supported Indian nationalists. But he also criticized the Swadeshi movement that many nationalist leaders in India liked. He liked self-help and learning. He asked Indians to accept "there can be no question of blind revolution, but of steady and purposeful education". Many people did not like his thinking. In late 1916, some Indians plotted to kill him when he was staying in a hotel in San Francisco, USA. When they saw him face-to-face, however, they instead started arguing with Tagore and changed their minds about killing him. Tagore also wrote many songs praising the Indian independence movement. He also returned the British honor of Knighthood as a protest against the 1919 Amritsar massacre. In Amritsar, troops of the British Raj had opened fire on unarmed civilians, killing many. Despite his unfriendly relations with Gandhi, Tagore played a key role in resolving a Gandhi-B. R. Ambedkar dispute which was about separate electorates for untouchables. Untouchables were people considered lowest in the social order. Rabindranath Tagore helped the freedom of India. He was first to identify the theme of ""Globalization"".
