Controversy On 1 May 2016, Adams sparked controversy by tweeting, "Watching Django Unchained-A Ballymurphy Nigger!" The tweet was criticised and subsequently deleted, with Adams apologising for the use of "nigger" the next day at Sinn Féin's Connolly House headquarters in Belfast. The tweet was widely reported in Irish, British, and American media. Adams said, "I stand over the context and main point of my tweet, which were the parallels between people in struggle. Like African Americans, Irish nationalists were denied basic rights. I have long been inspired by Harriet Tubman, Frederick Douglass, Rosa Parks, Martin Luther King, and Malcolm X, who stood up for themselves and for justice." On 4 May, he said, "The whole thing was to make a political point. If I had left that word out, would the tweet have gotten any attention? ... I was paralleling the experiences of the Irish, not just in recent times but through the penal days when the Irish were sold as slaves, through the Cromwellian period." He was criticised for perpetrating what has been called the "Irish slaves myth", by equating the indentured servitude of the Irish with the chattel slavery of African Americans.
