For those that don’t know a lot about islam:
The main difference between the Radical (let’s call them orthodox) muslims and the peaceful is that one group truly want to cut your head off, rape your children and plunder your goods (this is the standard business model of islamic society historically). While the “peaceful “ muslims don’t really want blood on their hands but would rather take you country by political infiltration and subversion along with rapid demographic increase. You will then be forced to submit to sharia.
As a side note there is no country in history that has ever managed to free itself from Islamic rule without outside help.
