The issue is also of world compatibility. Changing modern thought shapes a new world ethics today than the past. It is depicting loud and exclusive religionist as incompatible with secularist views based on new emerging philosophical thoughts. Churches in the west are gradually emptying and religious celebrations are getting more cultural, habitual or economics than truly religious. In the changing world, religions in its foundational form are getting more static, separating itself from modern time offering little values, except waiting for religious celebration except as a joy of long holiday, eating grand feasts and do nothing.
The question why Sikkism, Budhism, Judaism, Hinduism do not receive the same bad rap is because they are more benign from the worldview. Sikhs offer daily three meals free of charge, comparing to activism like benefits of Burqa, ISIS, Al Qaida, Taliban, Boko Haram, chopping heads, killing children in school shown on media for the world to see and form free opinion.
