I am with the opinion that she is matured enough to take her personal decision.
But she used Indian government and Indian public to gain publicity when she came in the tennis world at younger age. She was inspiration for all Indian girls as Indian girls doesn't turn at Tennis game. And now she is married with Pakistani man, none other than Shoaib Malik, who has broken rules everytime - be it match-fixing or his first marriage with Ayesh Siddiqui.
So overall, Sania has ruined her image which she had got 5-6 years ago. Now, every Indian hates her as every Indian loves to hate Pakistan, especially after terrorist attacks.
Don't get surprised if this marriage doesn't last long !!!
