MAF:Well put. Though additionally, some like to worship in a group as well as at home. We're generally gregarious creatures, wouldn't you agree?
I do agree. In fact we are biologically social creatures. Needing to be in a group was probably an evolutionary adaptation since we aren't physically a very strong species. I don't know how spirituality enters into evolution, but it is clear to me that our spirituality is also partially social, and that we will always organise groups around that, as we do around everything else.
There is something irreplaceably sublime about worshipping in a group. I don't understand how murderous fanaticism develops out of that. Maybe people confuse the sublime aspect of group worship with the more profane pleasures - inclusion, structure, approval - of group membership.
