Islam has pretty much every secularist principle in it, shame our people have a completely fucked up, false and a wrong idea of what actually secularism is.
Islam gives protection to non Muslim. Islam guarantees freedom of worship. They can consume whatever they like and their religion allows. Islam is the only system that has an obligation on the rest to help the poor and the needy, be they Muslim or non Muslims.
We are to provide justice and not take into consideration the faith of the accused. We are to be just, we are to kind and most of all we are to respect other's opinions and if we see from the example of Prophet SAWS we are supposed to be very patient.
Unfortunately, secular = infidel/la deeniyat in Pakistan thanks to mulla like Rampage, Zarvan etc etc.
