I did not say the tax has to be double, the rate can be decided by the state as to what's apporpriate. They should pay it as they are living in an Islamic land and being protected by Muslims. There is nothing wrong with them having to pay the state in return for offering them services. It will be beneficial to the state too as they have another source of finance.
As for number 4, they can't have major religious symbols in an Islamic land as that would no longer make it Islamic. They cannot hold any religious influence as that would persuade some of our brothers and sisters to leave Islam, either directly or indirectly.
When it comes to number 5, as I said earlier, making it public will deter people from committing the act. I guess if you want to publicly hang them you can, but if you make it an actual beheading the event looks worse offering more of a deterrent.
Calling Qadiyanis that other name is a disgrace to our beloved prophet. If they want to call themselves that fine, but I won't nor do I have to.
I understand why you might disagree with number 3, but please read my response to
@Zibago to understand why it's a good idea. You can also do further research yourself to understand why.
I am glad you agree with my thoughts in some manner, and that other members do the same. I will agree that Pakistan has some sort of an Islamic system, but sort of isn't good enough.
