The bloody attack on gay night-club in Orlando by a Muslim, the deadliest mass shooting in U.S. history, should be a wake-up call for progressives still unwilling to confront the illiberal core of radical Islam. The choice of target was not random, or just an expression of neurotic homophobia. Hatred of homosexuality is part of traditional Islamic sharia law, as is the punishment of death for transgressors. Today homosexuals are still being executed in Muslim majority nations like Iran, Syria, and Saudi Arabia. But just as Islamic misogyny has been ignored or rationalized by the left, so too has this violent intolerance for diversity.
