If you are a non-Muslim in a Muslim land you must conform to Muslim norms. Even if your ancestors have lived in that country for hundreds, or even thousands of years you are always at the mercy of Islam. Your existence is based on the whims of Muslims, and when they decide you are no longer wanted or welcome, out you go, in whatever manner Islam deems appropriate.
One tried and true method is to take over other religions holy sites and claim that they are a Muslim site, thus usurping for Allah anything which would challlenge Allah and Muhammad. This is the first of many take-overs in order to get the Sikh community to move. First Lahore, the other towns will follow shortly.
Islam has no patience for any belief system other than worship to Allah, and the Sikhs will suffer greatly, as have virtual;ly every other religion since the founding of Islam in 610AD.

Sikh community in Lahore prevented from celebrating festival
The Sikh community in the eastern city of Lahore has been barred from organising a religious celebration at a disputed gurdwara after a religious group persuaded authorities that celebrating the Muslim holy day of 'Shab-e-Barat' is more important than the Sikh festival.
The musical equipment of the Sikhs was thrown out and their entry to the gurdwara barred due to the efforts of the Dawat-e-Islami, a Barelvi proselytising group, The Express Tribune newspaper reported today.
Police were deployed outside the gurdwara to prevent Sikhs from conducting a religious ceremony until after the end of Shab-e-Barat, which falls tomorrow.
The Sikh community wanted to commemorate an eighteenth-century saint at the gurdwara on Friday.
Gurdwara Shaheed Bhai Taru Singh at Naulakha Bazaar in Lahore was built to honour the memory of a Sikh saint who was executed in 1745 on the orders of the Mughal governor of Punjab, Zakaria Khan.
Muslims do not want to be reminded of the fact that it is one of theirs who murdered this Sikh saint, so any celebration of that fact must be stopped. We can't offend or insult Muslims now, can we?
