Here is an excellent article which I hope you’ll read in its entirety at this link. This is the concluding paragraph, but this paragraph is twice as powerful after the ground laid in the full article.
History lessons are often incredibly simple and blunt, yet for all our powers of reason we often miss the most basic and uncomplicated of points. Peace-loving Muslims have been made irrelevant by the fanatics. Peace-loving Muslims have been made irrelevant by their silence. Peace-loving Muslims will become our enemy if they don’t speak up, because like my friend from Germany, they will awake one day and find that the fanatics own them, and the end of their world will have begun. Peace-loving Germans, Japanese, Chinese, Russians, Rwandans, Bosnians, Afghans, Iraqis, Palestinians, Somalis, Nigerians, Algerians, and many others, have died because the peaceful majority did not speak up until it was too late. As for us who watch it all unfold, we must pay attention to the only group that counts; the fanatics who threaten our way of life.
