Hearing the news over the past few weeks (and before) brings out the irony of people like Trump, who use the word "Muslim" to designate members of some evil sect. I need not ask "have they looked at the Quran?": they probably haven't heard of it.
Every human endeavor can veer towards evil (recall the Christian Inquisition in the 12th century). Indeed, it seems as if the greater the power of a religion, the greater the evil that it can fall into. There may be no hot line to righteousness; and yet, surely we can always discern love and beauty?
