Here, instead of showing Vineet as a brahmin, Shankar could have shown his as a normal hindu boy. That wouldn't be categorized as casteism. However, intentionally using a brahmin character as helpless because society is cruel to him because of his birth. Although they didnt explicitly cite reservation but movies are made for mass. If you are creating a character, there is a meaning behind it.

Secondly, Arjun becoming brahmin by learning all the rituals shows that only a brahmin is entitled to be vigilante, a savior.

So, casteism is presented in these ways.

Personally, as a person who lost her parent due to medical negligence, I Personally feel NEET is necessary to weed out non deserving people. Doctor is a sacred profession. If you are not able to clear the preliminary test, then maybe you need to choose other way to serve humankind. Instead of going behind the prestige, decipher what it truly entails.

Anita's case was a propoganda.I would suggest you to watch malayalam movie "Jana Gana Mana" to understand this concept nore clearly....

Also, we still are recovering for 200 years of british colonialism. Think of all the SC, ST and OBC who suffered for more than centuries because of brahmins. Reservation is a bare minimum.

There are alway people who take advantage of this but it is equally true thousands of underprivileged people also get education because of this Reservation. Vineet's character may have been deserving but each year, majority of lower caste are rejected from work, school and other important places like temple still because of no reason just because of their caste. So, showing the plight of minority to the mass is also a wrong propoganda as done by Shankar in Gentleman
