+1 on that. I only watched the action sequences in the movie as RRR is not the kind if movie I enjoy.
But the end of the movie, makes it quite clear that it is a nod to right wing Hindu nationalism. The most pointed example is the exclusion, in the end credits, of the 2 biggest icons of Indian liberation - Mahatma Gandhi and the first prime minister Nehru( the British locked him up for over a decade) who were secular liberals. Nehru happens to be the great grandfather of the main opposition leader Rahul Gandhi.
As the right wing Hindu pre independence movement largely connived with the colonialists, the right wing government today is focused on appropriating a select few independence fighters and projecting them as right wing icons even though they were liberals or socialists. 3 prominent figures.
1. Bhagat Singh - a socialist who is now projected as a right wing icon and stripped of his Sikh beard

2. Sardar Patel - Nehru and Gandhis colleague who had some right wing sympathies, but actually banned RSS (Modi's organization) following the assassination of Gandhi by RSS workers.

3. Subhash Bose - A foolhardy military strategist who tried to partner with the Nazis to fight the British. Eventually, assisting the Japanese in Burma and helping them invade India. Gandhi was extremely wary of Bose's plans.

Towards the end, it projects the independence fight as a largely Hindu fight against British and anoints upper caste Rama as a leader of lower caste Bheem. At this point, it seems that the exclusion of muslims, sikhs and some Christians etc. From the script as freedom fighters seems deliberate.
Bheem is a nod to lower caste icon bhimrao Ambedkar, who converted from Hinduism to buddhism to escape caste hierarchies. This could have been a positive inclusion in the story, but it is flipped on its head when Bheem is shown swearing fealty to upper caste Rama in the end. The Ramayana itself, has a negative attitude towards lower castes, which makes this highly improper.

Moreover the choice of Rama is sensitive in the current political situation in India as Rama is being used as a tool to bully poor Muslims on the streets.

[1] You will notice that Shambuka is noted as an "interpolated" character in Ramayana. This almost certainly true, but the Godliness of Rama as an avatar of Vishnu is part of the same interpolation. The original smaller Ramayana is simply the story of an "ideal king". This was converted into a story of divinity by the interpolation of Godliness, sexism and casteism(uttara and bala kanda) . Wikipedia has been edited to clarify that Shambuka is a later interpolation, while the article on Rama and Ramayana simply forget to headline that the divinity of Rama is a later interpolation. The interpolation makes complete sense as the brahmins successfully solidified the caste system and inserted casteist and sexist texts into several ancient sanskrit texts to anoint the caste system with divine status. There is a small ongoing movement to refer to the current version of Hinduism as Brahminism. https://en.wikipedia.org/wiki/Anti-Brahminism
