An atheist, however, doesn't end any discussion with the phrase "so God commanded!", an atheist only touches upon faith, although they can be annoying too.

A religious person doesn't either. But in a conversation about faith, both present "so God commanded!/there is no God!" as both the starting and the final argument.

Neither atheists nor believers have any arguments confirming their point of view.

Atheists have arguments, refuting another point of view :)

Well, this applies only to zealous atheists, those who do not allow for the possibility that they might be wrong.

It seems to me that any atheist a priori does not allow for the possibility that they might be wrong, because if that were the case, they wouldn't be called an atheist. The same is true for believers. Are they all fools? Perhaps, I don't even mind that thought.

Without a more or less clear ideology, a person cannot clearly know how to act in a given situation.

I disagree with that. Unless, of course, you provide some kind of real-life example.
