Sinn Fein leader Gerry Adams has waded back into the row over his use of the N-word after writing a blog post in which he frames himself as a civil rights activist.
The Louth TD's use of the N-word while watching Quentin Tarantino's film Django Unchained drew widespread condemnation.
Despite being forced to apologise for the controversial tweet last week, Mr Adams has continued to defend his comparison of the treatment of Northern Irish nationalists to African-Americans.
In a further tweet yesterday, Mr Adams shared a blog entitled "parallels in struggle".
He went on to claim in the lengthy post that there was no difference between the struggles of African-Americans and Irish nationalists.
He wrote: "What is the difference between the attacks on black civil rights marchers walking to Selma and white civil rights marchers walking to Derry?
"What is the difference between African Americans being killed because of their colour or 11 people in Ballymurphy being shot dead by British troops because they were Irish and nationalist?
"There is none. The struggle in Ireland is about rights. The civil rights struggle in the USA was about rights. The struggles in many other places around the globe are about rights. Sharing in solidarity is what we do."
However, his blog post came under fire from an academic.
Limerick historian Liam Hogan, who is researching slavery, described post from Mr Adams as "nonsense" and said that by writing it he was "damaging both histories".
Mr Adams also wrote that "in January 1967 I participated in the meeting that formally established the Civil Rights Association".
"It was inspired by the American Civil Rights Movement and consciously fashioned itself on it.
"Irish rights activists identified with the plight of African Americans," he wrote.
It comes after a host of political activists, commentators and senior figures in the civil rights movement lined up to dispute Mr Adams' claim last week that he was a founding member.
