How to deal with parents who hate chess ?

Chess totally improves concentration, strategic thinking ,patience and decision making . Only chess with its superior benefits can facilitate you hustling in some park at 5 bucks a game rather than making it at a real job. So if you are into food stamps ,wearing the same clothes for weeks and living in a crappy apartment with 15 other people you should not let your parents influence you.

In the US as many as you want. In Australia where there are more rules they don't let chess bums into the parks to start with.

Dunno what the Ozzi is saying but I am saying if you want to be a bum keep playing chess. So much for chess teaching you to think. Perhaps you should start with reading and comprehension before strategic thinking?

5 bucks an hour for blitz, that is 5 x 6 = 30 bucks per hour which is much more than the miminum wage in the US. Say a 40 hour week, you earn $1200, all tax free. You would put the other bums to shame.

how to deal with parents who hate chess ?
1. send them to bed with no supper.
2. put them in a hole in the garden with only their heads above the lawn surrounded by ants.
3. send them to go live with your younger sister.
What would your parents rather you do with your spare time? Watch television? Chess is NOT a waste of your time unless it is interfering with earning a living or somehow isolating you from everyone else.
Commitment to improving your performance in something challenging will always involve some general self improvement. It doesn't have to be chess, it could be many different things.
Of course it's also possible to play chess for fun and have no personal or chess related improvement.

when I was a learner, chess was fun. I remember sitting there thinking "i hope he doesn't spot that i left my queen en prise!" somehow the fun went out of it.

As in all things, it’s about understanding the other side. Why are they against you playing chess? Do they feel it’s a waste of those eight hours of free time you have, and that you should be pursuing some school or social life with your time? Are they domineering, and value the power of telling you what you can or cannot do? Are they insecure in their own intelligence and dislike their son gaining on and surpassing them? ;)
Unless you know why they’re against you playing chess, it’s going to be difficult to successfully convince them to allow you to play; likewise, without knowing why, it’s difficult to give good advice.
As a side note, it would probably be greatly beneficial to find some autonomy from them. I know the culture of India is different than my aggressively independent American culture, but you can’t become your own man / person until you begin unshackling yourself from your parents, especially in a situation like this. My two cents, at least.
I will invite a dinosaur to dinner
Dinosaurs donot exists
