"However, atheistic materialism not only promotes self-interest, but DICTATES it albeit unknowingly to most"
Mhm, rather than spending my life flogging myself for an imaginary being I can go enjoy my life.
"In atheism, there is no objective reason to be moral other than the mystery 'human values' you arbitrarily conjure up."
Projection. You may not care for other human beings, but the rest of us do. "Human values" is actually quite a powerful force.
"There is EVERY good reason for you to look out for number one and to rape, kill and dominate everything that crosses your path."
Nope. To do those things would bring misfortune in the form of law, societal castigation, and heavy conscience (That thing that you profess to lack).
"You should be the ultimate indulgent."
Well, yes, for the most part I live for more than obtaining sacrifices for a sky fairy. Oh the horror.
"There is absolutely NO good reason why you shouldn't be, the only thing holding you back is your cowardice to step on other people's toes."
Oh yes, not wanting to be the subject of a witch hunt, and wanting to maintain a place in society, with friends, responsibilities etc - what a coward I am for wanting such pleasures. Of course it's the ultimate sign of bravery to refrain from killing etc solely because your imaginary friend threatened you with eternal damnation. What a chivalrous knight you are.
"Not that it matters, since there are no meaningful consequences and you merely 'fall asleep' at death anyway."
I'd prefer that be later rather than sooner. Why shave 60 years off my life that I'll never get back?
"Why not live life to its sickest, most brutal 'fullest'? "
Because tha would not be pleasurable in the slightest, and would drastically shorten the span of the only life I am going to get.
Unlike you, of course, who can brush off the consequences of your behavior by apologizing to a sky fairy and live forever. And you accuse us of impermanence?
