Want lots of terror gangster attacks ? Import lots of islamonazis.
Islam is incompatible with a free society. Muslims who follow the Koran have no intention of assimilating. They intend to conquer and subjugate everyone. If there are moderate Muslims, they are heretics according to the Koran. As far as I know, it is the only religious text that commands its adherents to force others to convert until the entire world is governed by sharia.
The terrorists are winning because the West have let Domestic Terrorists vilify masculinity.
