Buddhism, Catholicism of several stripes, Hinduism.... Pretty sure there are more. Taoism. Confucianism. Mostly eastern or native religions, but not all. Being eastern or native does not render these faiths invalid.
What bothers me is the notion that there is no afterlife, and/or no way to benefit the deceased through religious practices, and the deceased person doesn't and/or cannot, care, and so it doesn't actually matter what is done as long as the people arranging whatever IS done, if anything, are happy with that, and furthermore, and mostly, that this is the only correct and reasonable modern social attitude.
While funerals do have some benefit for the living, as ViolinP suggests, they aren't all about that, and I think implying or flat out stating otherwise disregards the beliefs of those who believe certain services actually do matter to and benefit the deceased, even though they are deceased.
My point, I guess, is that plenty of faiths allow one to benefit the deceased, and these are important, and should neither be disrespected nor disregarded.
