Seriously you have a severe problem in understanding simple English.
Where did I say without believing in Allah you can be a Muslim. Of course Allah will punish people in the hereafter according to Islamic faith. We are discussing the role of a community not the punishments in the hereafter by Allah.
I proved you from Quran that Islam endorses a secular system, which ensures religious freedom for everyone. I am not defending the secular system of Switzerland or EU. I just gave you evidence from Quran the Quranic secular system. All religious crimes have to be left to Allah for punishment, giving complete freedom to individuals and groups to practice their faith. The maximum you can do is to inform them the message of Allah. For the social governance leave Islam out of it to create an Islamic secular system. A clergy system being followed in a lot of Muslim countries where others can not follow their faith is against the teachings of Quran!!!
