Wtf are you talking about? When am I saying I don't want to take care of my heritage? I love the temples here in Pakistan especially the tall ones, if Hindus want to preserve these temples then they should do something about it.
It is not the responsibility of Hindus alone ... for example, most Afghans were quite distressed when the Taliban destroyed the Buddha statues. Even though Hinduism and Buddhism have been wiped out from Afghanistan, Afghans realize that this is a part of their heritage and history.
