Thanks alot. There are, however, divergent perceptions of death rituals that emerge along, for instance, lines of gender, ethnicity, age and social group. Contested views of highly visible public funerals, for instance, mark different levels of social involvement and personal identification that affect emotional experiences and memory.
OK, because of all the commas in the sentence it's difficult to see. "Lines of gender" isn't one item in the list. [Perceptions of death rituals] [diverge (go apart)] [along lines of (according to)]
gender (male and female)
ethnicity
age
social group
So each one of these categories has different perceptions of death rituals.
