This thread has made me so sad.
There are so many revealing attitudes on this thread, but one that comes through is that we in the west, well the UK maybe and in modern times, don't deal well with death? I presumed that the rise in direct cremation was about the expense - totally understandable and also perhaps about not wanting to burden others with dealing with complexities of funeral arrangements - which I get, but find very sad. The only relative I know, who had a direct cremation really didn't want any one to have to deal with it all and perhaps wanted quiet discretion. We respected that, but my OH and I still regret (and this is 15 years ago now) that there was no formal ceremony for such a lovely person - and yes that is about us, but it affected so many in the family and friends. To have someone just gone makes it harder to deal with.
The funerals I have been to, some devastating, some inevitable, some complicated have often been really good occasions, full of love, comfort, connection and celebration. The gathering of distant relatives, friends not in contact for years felt important, the impact of a life remembered and actually pretty wonderful amidst the sadness.
I understand totally that that is not always the case and empathise especially with the PP above who has nursed her mother and has no more space to give to funeral arrangements right now.
I am not religious, but I really appreciate traditions and rituals, they are some of the few things that are genuinely and authentically social. We considered our wedding was not just for us, it was about marking a change in our lives within our community and family. I think this is something explicity stated in the Christian ceremony? Sometimes it's not about individuals (beliefs, needs, preferences whatever), these are the rituals that hold us together, accountable, as social beings.
I wonder if the OP has considered that pretty much no one wants to go to a funeral - its hard and upsetting, but that it's part of a social duty that binds us with family and community and is an important ceremonial marking and processing. As others have said death rituals have been part of human society since humans have existed and are significant accross the world - there are reasons for that. I find do find the practical solution of direct cremation quite clinical and dehumanising, like a tidying up or simply a disposal, almost a denial of a life (and a denial to people to grieve how they want or might expect to), but as I said I do understand why some people want that.
I think you missed out OP, and I think priviledging a preference, presented as belief, was really unfortunate and pretty selfish.
