I am not a "common atheist " so I hope my arguments are better.
#1. I see where you are going with philosophy of what a person accepts, so feel free to examine anecdotes and whatnot. Many uncommon atheists (and some common ones) recognize that there is very little absolute evidence in the universe for things of nature and science, so we weigh evidence for its value. Fossils being where the theory say they should be are accepted, theories that account for all known variables are accepted. Each must weigh these for themself. As for me, anecdotes are weak, especially when I can find people of varying faiths swearing by an anecdote being a proof of their different beliefs.
#2. The multiverse theory is mathematical and not "universally " accepted. And it doesn't address the very beginning of the mass-energy. We just don't know enough to accept that. But accepting and theorizing are different. We make progress by considering possibilities, especially those that fit known data. You feel free to personally reject multiverse and dark matter/energy theories, string theory, yadda yadda. Keep in mind that theories might have more evidence in the future (like black hole theory ) so that's part of pondering and examining.
#3. I wholeheartedly disagree with you on the moral values of Yahweh. You don't need something outside of humanity to judge Yahweh's treatment of humanity. If you attempt to compare God's treatment of men to men's treatment of animals, men have failed and God has failed (if "God" is Yahweh of the Bible). It is ludicrous to figure that lowly humans being treated poorly just don't understand and cannot judge because the being treating them poorly is superior. If you mean we are animals or pets to God and we deserve similar treatment as that which profit driven companies like Purdue Chicken dish out to chickens, then why worship such a bastard?
I will leave the rest for another time.
