We need such things every single day and everywhere not just one day of the week.
To be honest, people just rave and rant or ignore or forget.
Let me reference RDB here. After that film, several youth started forums online and groups in real life to discuss social change, many got into activism, there was whole wave of ''be the change'' and patriotism, citizens taking action to make country perfect.
It lasted for a year, intensified with Lage Raho Munnabhai also. Later it began to taper off.
Today, only a few activists and ''enlightened'' youth from that time are still continuing their work - be it writing or doing actual activism or joining IAS/IPS instead of corporate sector. Others just quit and now cite ''job'', ''studies'' or ''marriage'' as excuses for leaving their ''desh ko perfect banaana hai'' mission.
The problem is we have way more options (and sadly way more tendency) for escapism and inaction, than working to change our attitudes or do something for society. So we continue being led by culture, stereotypes (reinforced by media, society, family etc.) and knowingly or unknowingly help propagate stereotypes and social evils by transferring similar attitude in others around us and younger generation.
Problem is never with shows like SJ or NGOs or any movement. Problem is with US. I also debate a lot and feel pinched when I see on one hand we debate on issues and on other hand we have kids employed at college canteens. But what have I done for it? Nothing. I just ranted and vowed not to employ kids as domestic help in my house. But it would have made a difference had I protested to college authorities for allowing under age workers in canteen.
I routinely point at my relatives' language, and tell them to avoid using words which are racist, casteist or stereotypical. And I get laughed at for taking things too seriously or ''literally'' and I am told it is just commonly used language.
Honestly speaking a socially concerned person is usually laughed at, told not to think too much and instantly dismissed as odd or pakau.
I have had enough of so-called friends avoiding me or teachers telling my parents that I talk or think too much - when I would point at casteist remarks or didn't laugh at caste or religion based jokes they ''casually'' cracked.
There's always a pressure to be passive and to conform to existing ''norms'' - bear things as they are.
