Informed and influenced by Ahmed Sofa's thoughts, his exploration of Bangladesh's politics and culture has a significant following among the country's young generation of writers and thinkers.

Khan translated the works of Plato, James Rennell, Charles Baudelaire, Frantz Fanon, Dorothee Sölle into Bengali.

[citation needed] A proponent of anti-colonial movements, Khan has engagements in the regional political economy and culture from a Lacanian-Marxist perspective.

[16] From this perspective, he has written on the works of Charles Baudelaire,[17] Walter Benjamin, Michel Foucault,[18] Frantz Fanon, Claude Lévi-Strauss, Edward Said,[19] Aime Cesaire,[20] Talal Asad[21] and many others.

[23][24] Salimullah Khan wrote on Lalon Shah,[25] Ramaprasad Chanda,[26] Jasimuddin,[27][28] Roquia Sakhawat Hussain, Ahmed Sofa, Abul Hasan, Tareque Masud[29] and some of his contemporaries.

Khan views Kazi Nazrul Islam as an anti-colonial and democratic thinker cherished dearly by the people of Bengal.

[39] In Khan's view, the three fundamental principles of the liberation war of Bangladesh are equality, human dignity, and social justice.

[58] He defends the equal right of all communities to observe their respective religions,[59] and believes that proper education and guidance is critical to dissuade the young generation from going down the path of extremism.

[61][62] He opined that without establishing Bengali as the main medium of education in all stages, the decolonization process would lag behind, and the Anglocentric colonial cringe would persist in the social dynamics in Bangladesh.

[63] Citing Freud and Lacan, he wrote that the people of the ruling class are pervert since their acts and thoughts do not reflect their words.
