There is enough evidence on record to show that Gandhi's views on casteism and racism changed with time. Therefore selective reading of Gandhi will definitely lead to wrong conclusions and we can see many scholars have fallen into this trap and have done disservice to Gandhi and Gandhian thinking.

Gandhi of Quit India Movement was entirely different from Gandhi of South Africa as seen through his writings and discussions, especially with Goparaju Ramachandra Rao, known by his nick name Gora. Besides Gora another big influence on Gandhi to change his views on Caste system was Ambedkar.

Gandhi of early decades of 20th century wanted to demolish untouchability but he was still committed to caste system.

But by 30s his views started to change. Anurag Bhaskar points out (https://theprint.in/opinion/this-leader-forced-mahatma-gandhi-to-change-his-views-on-caste/128108/) that in 1921 he wrote in his journal Navajivan, “[I]f Hindu Society has been able to stand, it is because it is founded on the caste system”. But on 16 November 1935, he wrote in an article, “The sooner public opinion abolishes [the caste system], the better”. The article was published with this title in capitals – ‘CASTE HAS TO GO’.
Bhaskar further writes that as "Independence neared, Gandhi became radical in his ideas. When he went to Noakhali in eastern Bengal (in January 1947) to tackle the communal violence there, he gave, as Rajmohan Gandhi calls it, a “radical advice” to the upper-caste Hindu women. “Invite a Harijan every day to dine with you. Or, at least ask the Harijan to touch the food or the water before you consume it. Do penance for your sins”.

Gandhi also said he will bless a wedding between Dalit and non-Dalit.

At the Jaipur Literature Festival in 2018, Indian American writer Sujatha Gilda termed Gandhi as a “casteist and racist” as in South Africa he said “black” people were “kafirs” and “losers”.
It is quite clear Gandhi of that time (1908) was not ready to be equated with natives. But Gandhi was still young, 27, and evolving. Who better to judge Gandhi here than Nelson Mandela who said: "
Gandhi must be forgiven for these prejudices in the context of the time and the circumstances.
