actually you said that since there was the Inquisition, religion was mistaken or flawed, as if it was supposed to be perfect!! Isn't thinking fun??
And you are saying that since there was Stalin and Pol Pot, atheism was mistaken or flawed. So why are you so harsh to judge one and be so soft on the other?
Besides, many atheists think all these ideas are human ideas: sometimes clever, sometimes flawed, imperfect experiments to see what works and what doesn't. Sometimes some things blow up in our faces. Other times they work out pretty well. But it's all human.
But if you are going to claim that you know divine revelation, or your religion gives you some insight into right and wrong which the rest of us don't have, you have to show us that your most current opinions on how we should be doing everything are absolutely divinely perfect. Looking at history, all we see from religious people is people claiming to know what divine revelation is, and coming up with many crazy ideas and ways of doing things no less prone to errors and blowing up in our faces than other human ideas, like the inquisition. That's what makes us start to think that these things you claim you know are divine revelation are nothing more than your own most current best ideas projected to the heavens and the gods. Besides, you yourself claim that Christ left behind very little in terms of anything solid or concrete instructions and guides. So I am not sure where you are getting all this confidence in knowing detailed domestic and foreign policy issues from reading the Bible, unless you are reading your own opinions into some very vague and abstract things in the Bible, like one would read Tarot cards or something.
So you have 2 choices left, it seems to me:
1) claim that your most current recommendations are based on a very confident and sure understanding of divine revelation, and therefore guaranteeing us that if we implement them, THIS TIME, unlike other times, everything is going to be perfect,
OR
2) You don't know what you are talking about, and "Christianity" is nothing but a projection of your own current, very human, very fallible opinions, onto God (eg, the Dakota pipeline is God's will, or an invasion of Iraq is God's will, etc... will as it says in the Bible...).
I don't see a third option. So which is it?
