No definitely not.
An atheist isn't a religion its just a group name for people with no religion. Atheists have the freedom to believe what they like about violence.
Violence has no color and criminals have no religion.
The answer you are looking for is Catholic and Protestant. However it would be wrong to categorise the violence in Northern Ireland as being down to religion. There are many factors, of which religion is just one. The two sides roughly divide by religion, but there are other things that divide them that have nothing to do with religion, and many of those that were involved in violence were obviously paying no heed to what their religion would have them do. Neither Catholicism or Protestantism support violence.
Peace
