I think the arrogance comes out when those who are religious insist on telling atheists what it is we believe.

As I said, atheism is not a Faith, with a capital 'F'. I can only have faith in that which has some evidence, not have faith in a 'nothingness'
What you believe is fine, it's just not something I have. So therefore not a Faith.

If I told you that you were not a real muslim because you lied when taking the Shahada because you are uncertain that Zeus, Odin, Shiva, Pagan tree spirits etc do not exist, you only have faith that they do not (ie There is no god but Allah, but I am willing to entertain the idea that there may be other gods because I can't be sure)- then you would quite rightly think I was telling you what YOU believe!

Now I am not saying that, just giving an example based on your idea of what 'faith' is.,

not including the victims of Noah's flood, Sodom and Gomorrah, or the
many plagues, famines, fiery serpents, etc because no specific numbers
were given. Satan - 10."
