No. This massacre is explicitly ordered by this "all-loving" god,
I already answered this...the Israelites would, inevitably, battle some tribes. That's how things would go down anyway. That was the world then. For God to come down with a message of a united humanity, through love, would be unheard of at that time. To give you an example, at about those times my predecessor came down and slaughtered the pre-Hellenes, occupying their ground. And they had religion, a polytheistic one, only no universal laws as "you shall not kill", not ever for their kin. Just offer the required sucrifices, do not commit hubris, and...yeah, that's it. God protected Israelites so, one day, the message and the Laws would be spread to humanity, just as they did.
We have to see things in their temporal framework. Jesus came with that message of universal and unlimited love ~1000 years later, still most didn't accept it, and 2,000 years later, now, still most don't accept it, not really. Israelites weren't ready for it, nobody on Earth at that time was, and they were a tribe struggling for survival for decades in the desert, with other nations on their back. They would go to war, and they did. Between then and now, we have Jesus that shed a new light to all this.
You know, let's turn this a bit on its head. Let's say you have all compelling evidence against the existence of God, or that my God is a sociopathic murderer. Congratulations, what have you achieved? Now I'm back into believing that life and existence is as chaotic and random as ever. So? What's changed? I myself are all for science, and think Creationists, for example, have lost the battle before it began(I'm not so sure why people like Dawkins still continue the battle, doesn't he have actual students to teach about actual science and not disproving symbolic images?). I do believe in the Big Bang and evolution, although to be honest in reality I shouldn't give a rat's ass about all that, since they don't affect my everyday life at all, nor do they teach me how to be a better person.
Great, so I believed in a good Creator that gave birth to the Universe and who is trying to teach the human race how to be good by entering history Himself, and you demolished that "myth". So what? You really think wars will stop, bankers will stop being greedy, people will stop murdering each other or telling lies? Does all that happen because some people believe in a God that explictly commanded not to do those things? You focus too much on the bad things that religion causes, probably because of your experiences you shared, that you don't look at the good ones. Do not murder. Do not steal. Do not lie. Love your neighbour as yourself. How can all this be "bad"?
The same way Creationists are fighting a lost battle, you on the "other side" are fighting again a lost battle. Religion doesn't seem to want to go away. It probably never will. I keep hearing arguments against an even liberal interpretation of the Bible, as in "this proves that the Bible is not God's word if it gets reinterpreted every 100 years". Why the fuck do atheists even care about that? This is crazy. You are offered a solution that is half-way there, and some go "no, we should abolish religion alltogether". I'm sorry, but that makes no god damn sense. People will not quit their faiths because Dawkins "disagrees". Dawkins in an expert on biology, not in life in general, life is more than the sum of its parts. Those people need to learn to compromise. A future with atheists and non-bigot religious people co-existing is not a bad future at all.
And lastly, atheists are not ignorant-safe, you know. I watched one Dawkins interview where he said that the "gap" that would be left with religion gone, could be filled with "philosophy and science". Yeah, Richard, could I interest you to some Plato or Newton or Leibniz? Or would it be Dawkins-approved literal works only?
Things aren't black and white, not from our perspective anyway.
