I'm afraid this will never go away if u look back through the history books most wars stem back to sum form of religion some of the worst things that have been done to people have been done in the name of a religion which I will Never understand as in the bible it says thy shall not kill lol can't speak for other religions , extremists will always be around I'm afraid as people beliefs and views will always be around ultimately regardless of religion where u live you should obey the law of the land as u have chosen to be there so should follow the laws that are there be respectful and mindful of others beliefs but do not force your beliefs on others peace is not something out of reach but seems to be something that many religions are not interested in as they all strongly believe that there is the right path to choose and we should all follow or be damned it's those kind of views that keep the killing going
