Why does culure not matter any more?

[postage]

Correct me if I am wrong. If a child has been brought up in a certain culture ( not religion) then why is it when they meet someone from a different culture they forget the values of there own and adopt all the good and bad from the other
My mate's son was brought up in a British Asian culture with good and bad and as soon as he met a girl from far east couple of years ago he changed, he no longer wanted to talk to his mother or family. He forgot all he bad times they put up with for him and all the love they have for him.
When the mum asked him to do something which is related to culture he refused and did, not see the importance of it. Without culture out lives would be very bland and boring we would not have the different values??

True or false?

FALSE;(the example you give)The Universal problem is not one of 'Culture' or nuture, It is much older, instinctive and rarely overcome however religous or familial culture attempts to harness it.
It is the nature of the beast-to follow its own path, map its own destiny-to fight perceived captivity.
The most hurtful and damaging is the 'Rebel Without A Cause'-the square peg in a round hole, it can be made to fit but force it and both peg & hole will be damaged, leave it to wear away in its own good time and neither notice the change its just accepted as being so.
