Mohsin Hamid in Dawn:
The reason can’t be that their large numbers pose some sort of ‘threat from within’. After all, Ahmadis are a relatively small minority in Pakistan. They make up somewhere between 0.25 per cent (according to the last census) and 2.5 per cent (according to the Economist) of our population.
Nor can the reason be that Ahmadis are non-Muslims. Pakistani Christians and Pakistani Hindus are non-Muslims, and similar in numbers to Pakistani Ahmadis. Yet Christians and Hindus, while undeniably discriminated against, face nothing like the vitriol directed towards Ahmadis in our country.
To understand what the persecution of Ahmadis achieves, we have to see how it works. Its first step is to say that Ahmadis are non-Muslims. And its second is to say that Ahmadis are not just non-Muslims, but apostates: non-Muslims who claim to be Muslims. These two steps are easy to take: any individual Pakistani citizen has the right to believe whatever they want about Ahmadis and their faith.
But the process goes further. Step three is to say that because Ahmadis are apostates, they should be victimised, or even killed. We are now beyond the realm of personal opinion. We are in the realm of group punishment and incitement to murder. Nor does it stop here. There is a fourth step. And step four is this: any Muslim who says Ahmadis should not be victimised or killed, should themselves be victimised or killed.
