I was taking part in the discussion and bringing a pagan polytheistic perspective (which is very much a minority in these sorts of discussions.)
@Mistyglade
Speaking as a person with religious views here (I am a polytheist pagan occultist) - I personally do appreciate the planet (well, the nice bits, anyway.) A lot of Pagans enormously appreciate the beauty of the physical world, as respect for nature is built into a number of pagan practices (but paganism is so big and diverse that you don't have to venerate nature in order to be a pagan - I'm just pointing out that a love of nature is quite common.)
Regarding blowing things up, I don't think you'll find any reports of pagan polytheists doing any such thing, so...
I don't think the present is less important than the hypothetical afterlife. (I also don't believe in the concept of a Heaven/Hell or places of eternal reward or punishment.)
However, some people do like to think about the concept of a life continuing on from this one and try to formulate their perspective on it. I would argue that there are justifiable reasons to believe in some kind of afterlife; people have personal experiences which they interpret to suggest that there is some continuation of life. There are people who have experiences in which they appear to have contact from deceased spirits (mediums.) Parapsychology research into mediumship has yielded some data which suggests that at least some mediums might be communicating with something/someone beyond this world.
