Really? I'd say, money is and God can be only a disguise for it. Isn't it a space to argue against money in todays world? Money do exist, so it's even easier to point out the hypothetical harm they do: stealing, murders, wars etc.
There can be many excuses. What I mean is this. Religion is by definition exclusionary.
You are with us,
that guy is not. We are a group, he is excluded. He can join if he meets our conditions, but only then. And this is logical. There is no point in having a "special club" if anyone can enter and exit anytime they want.
Now this has nothing to do with God, but the way they justify this is "god said it". We are the chosen people etc.
And that is one of the most insidious things about religion.
Of course there are many other problems in the world.
Have you heard of deists? Pantheists? They present a rather imprecise concept but still valid according to some well known philosophers in the history. A concept without a religion in the background.
Well deists I think are equally vague and silly, but pantheism is just a nickname. We call the world god. That's not conceiving anything new, it's just renaming something old that we see and know.
Let me ask you: have you completed any philosophical or theological training? Not particularly an academical education, but amateurish one, just for yourself? Or do you only try to explain everything by logic (I have no doubts you're a great logician, you're a programmer after all and you may also be very well educated in maths while attending to Polish schools, if you attended here) without a theoretical basis?
No, I have no such background. I'd like to cover some bases in philosophy actually, but this is a rather newfound interest of mine and I haven't done any such exploration in the past. On the other hand, there are many competing fields for my attention.
And no I didn't go to school in Poland, I did my schooling in Norway.
