The question of whether Islam is a threat to the west (which I certainly don't think it is) is not relevant to the matter of Tommy Robinson and his Pegida stuff.
Allegedly Robinson is worried about Islamic extremism, and who wouldn't be.
But his response to that is in my opinion and the opinion of many, hopelessly misguided. He wants easy solutions to complicated issues, and so it seems do many people on here.
I don't wish to give people like him and his follows the undeserved courtesy of entering into a debate about religion, a subject that bores me to death.
