We just cannot put the equal sign between Muslim and crime.
I was just talking about Indonesia, which as you know has both Christians and Muslims, so no mention from me crime=Muslims, but to be honest very time I hear about terrorist attacks I think Muslims straight away, I guess its the times we live in today.
If you Ignore crime you have to admit, Islam is not compatible with life in Poland, in fact there are a great many things in Poland that are haram and the punishment would be most severe in a Islamic country.
I don't understand why a Muslim would wish to live and bring up children in such an environment, I certainly would not live in a Islamic country because it would not be compatible with my way of life, In fact I would either be severely punished or worse.
