Times LIVE said that in the 1980s, Roodt was an anti-establishment anarchist, but that now "he is branded a right-wing reactionary" for his "vehement anti-ANC essays". Two of his literary works had been banned by the South African government in 1980, a time of strict censorship.
After returning to South Africa in 1992, Roodt worked for Citibank until 1999, and in 2000 he co-founded PRAAG (Pro-Afrikaanse Aksiegroep, or Pro-Afrikaans Action Group), which describes itself as an extra-parliamentary movement devoted to the rights of Afrikaners. PRAAG also has a publishing division, which has published some of his recent works. Roodt has contributed articles to Focus, the journal of the liberal Helen Suzman Foundation, columns to American Renaissance, a white nationalist magazine, various scientific or academic journals in South Africa as well as a host of articles in South African newspapers. He has also appeared on television and radio talkshows in South Africa.
In May 2011 Roodt stood for the Freedom Front Plus during the municipal elections as a candidate in Johannesburg but was not elected.
Roodt is the deputy leader and spokesperson of South African right-wing political party Front Nasionaal formed in late 2013 which promotes separatism and Afrikaner self-determination. The Sunday newspaper Rapport reported on 8 February 2015 that Roodt had been "voted out of the party" without his being aware of it. He was quoted in the article as saying that "he would henceforth be devoting his energy to his publishing company, Praag... I am disillusioned with Afrikaner politics. I am finished with Afrikaner politics."
