must be stopped. extremism must be stopped. >> paul: immigrants who have come over from pakistan and keep traveling back and forth at some point do you expel them or do you -- do you ask these people about their religious beliefs before you let them be it citizens? >> i think one should. i think that with so much of the islamic world having fallen prey to this very mill tarized, radicallized, threatening set of beliefs, i think one should do that it is very important, that a large number of muslims in britain and everywhere else are not radical. they live like you and me, raise their children, have a good job, benefit from the human rights of the west. we must not demon -- demonize all muslims.
