How do you get to be as judgmental as that, Wolfie?
Your version of reality is obviously the version you - and you alone - declare it to be.
Every atheist is doing pretty much the same thing as you.
How do you see society functioning with every member inhabiting a different 'reality' from everybody else?
Every human is doing the same thing as me. We are all arguing from our frame of reference. Some people include super ghouls and ghosts in their frames, others do not.
How would I see society functioning with everyone inhabiting a different reality? Much like it always has, where everyone does inhabit a different reality. That is why religion has been so successful, because it helps us all conform into single realities.
My utopian ideal would simply include a religion that venerates the truths of science and reason. Of course not all things in buzzwords like "science" and "reason" are true, but these things and their debate and discovery would be the religion.
Humanity should look at everything biologically. Treat the planet as if we were an aquariest and the planet is our tank. Human behavior is all ultimately rooted in biology. We should remove prexisting morals, and start again fresh. For many, that seems like it ignores a spiritual component, but I would counter with the idea that humans need gratified on spiritual levels as our biology dictates, so this is not exclusive.
