My view and reasons for them. Atheist and Christians welcome here. (short)

[Quick]

It might be a big deal if theists could agree on what a "god" even is. If that thing is an unfalsifiable being, then it's an utterly irrelevant issue.

The actions some theists take based on their belief is a big deal though.

If something is done because of a specific thing (belief in a God in this case [doesn't matter if/what they disagree on and what the specifics of difference these beliefs are]) and it has a drastic effect on humans, then it's a big deal.

I would say belief in God is probably one of the most influential things that has happened to humans, psychologically speaking.

I think it's not entirely honest to say atheist (who have made a stance on the belief in a god(s)) are completely immune to causing a reaction to/from other people. I think as soon as you make a stance in any form whatsoever that you have entered the arena.

I don't think belief or lack of belief in unicorns is the same sort of thing here. I think we are talking about a MAJOR difference in perspective that has affected the humans on the earth for a very long time (Israel going to war against those who don't believe the same thing for instance). When we are talking about a belief or lack of belief in something that has been so influential to humans it's not the same ball game, it's not even the same fucking sport (Pulp Fiction reference, just because I can).

Sorry Quick. I beg to differ. They are exactly the same. Don't be fooled into thinking that just because it's had a huge impact on the world, that the core proponents of the belief must be true. Otherwise you'll need to agree that Allah is true, and all the other deaths and wars fought over different Gods...
That's just the "Argumentum ad populum" fallacy... The Fallacy of Popularity. If something is popular, it must be good/true. Wrong!

80% of the world is religious. But they believe in many Gods. They can't all be real, can they? But they can all be false.

I am not saying that just because it's had a huge impact on the world, that the core proponents of the belief must be true in this case. I am not arguing the validity of the claims that God is real or not here. I am simply stating that because there are very strong opinions about a certain topic and that these opinions on said topic are very far reaching throughout the world that no matter what stance someone makes on said topic that this means it will affect one's worldview.
