I think they meant that having a Dalit man be presidett is proof that there has been some progress, same as Obama's presidency in the US. That showed that progress has been made in the battle against racism, even if it certainly doesn't mean that racism is over.
The president is not an elected post but a selected post. They selected a dalit exactly for this reason the person above states. For tokenism. The current govt is a Hindutva ideology based govt meaning they literally believe Dalits are just lower humans. The president from a dalit community was just tokenism.
Please ignore their reply. Our Prime minister, which is the most powerful position in the country, is also from a 'lower class'. They're deliberately giving it a negative spin as it suits their policial viewpoint.
I understand that possibility, but their reply is still right in that a named position is fundamentally different than an elected position, which I assumed the president to be. That of course does NOT mean that someone being named to such a position is automatically tokenism.
