The majority of Rangers and Celtic supporters do not get involved in sectarianism, but serious incidents do occur with a tendency for the actions of a minority to dominate the headlines.[1][2] The Old Firm rivalry fuelled many assaults on derby days, and some deaths in the past have been directly related to the aftermath of Old Firm matches.[36] An activist group that monitors sectarian activity in Glasgow has reported that on Old Firm weekends, violent attacks increase ninefold over normal levels.[37] An increase in domestic abuse can also be attributed to Old Firm fixtures.[38]
