why all the religious violence today? are the christians as bad as the radical muslims or jews?

Answer 1

Currently Muslims seem to be the most violent religion but all religious groups have violence in there past. Today's Christians are not as violent as the Muslims but religious extremism always has the potential to lead to violence.

Answer 2

The only thing keeping christians from returning to the good
old inquisition days is the separation of church and state
here in the USA.
Religious mentality hasn't progressed much past the way it was in the year One A.D.
