Firstly, cartoons aren't teaching bigotry. They'd be teaching bigotry if they show murder of muslims or any other such thing. I don't see how they teach anything other than mythology combined with the virtues associated with those stories.
Secondly, and more importantly, banning is always despotic and fascist. It is knee-jerk reactionary, serves no positive purpose and is merely controlling the lives of people.
Why shouldn't parents be the ones who control what cartoons children are seeing? Are they too damn lazy to check what their children are seeing? Or are they incompetent, unworthy and uninterested to check what their kids are upto? Or are that kids of this age sneaking around to watch these cartoons surprising their parents? It is not the state's job to determine what you see on television. Parents should act as the censors in this regard, not the state.
Create your own rival series so that people can listen to your own fiction and hagiography. Until then, let parents do what they are supposed to do. State should not intervene in these matters.
I have no qualms (frankly have some qualms) with parents controlling what their kids watch and perfectly fine if they choose to restrict their kids from watching hindu mythology cartoons.
I cannot in any way support state taking action in this regard. It is not the state's job nor its purview. This is infiltration in the lives of citizens. This is despotic and fascist and not different from banning books that are rival to state sponsored ideology or popular citizen views. Controlling mass media and literature is fascist. I repeated this last time we discussed banning Indian channels as well. I genuinely hate Star Plus and the likes but cannot support banning them. State should not interfere in these matters.
Banning anything is Fascist. No debate.
