You ever notice that, on the whole, messageboards tend to have more horrible news stories than good ones? And when the good ones are posted, at least 5 people have to comment on how this renews their faith in humanity, that it's about time an uplifting story was posted, finally, I needed a feelgood story this week after that story about the kid being raped/killed/murdering someone, etc.
As if the good stories are so rare that they feel the need to point out how rare the good feeling is.
And then, on the flip side, whenever a horrible story is posted of, say, some pedophile, some abusive parent, or yet another school shooting, people react badly, but it's a clockwork badly: Ugh, faith in humanity -1, stories like this make me fucking sick, I hope that guy rots in prison, this ruined my day
, etc.
People have seen so many horrible stories that they're USED to it and are also used to their own impotence at being completely and totally unable to do a single thing about the overwhelming tide of rotten people out there.
Religion is the same way. Regardless of your religious beliefs, you'd have to be in denial to not notice that an IMMENSE percentage of those horrible stories are also religious in nature. Pedophile priests, another religious school denying science, religious-fueled murder and violence and death and war always happening somewhere in the world everyday...
There's just so much negative press every day about the latest religious-fueled atrocity.
Now, the critics of religion know they can't
really do anything. No atheist is going to do a damn thing against the power of religion (at least not right now). Ranting online means nothing in the long run. But they have to feel like they're doing SOMEthing. So the criticism of religion is the attempt to feel less helpless in a tide of poison, especially when said tide is being supported (for good or bad) by religious supporters.
So, just like the clockwork reaction to negative news stories, all they can do is lash out online, a sad lament that nothing will ever change and humans are just horrible creatures. This means that those one-shot good religious stories are just like one-shot good news stories. There's just so much negative news about religion that the good deeds are almost...fake.
Fake in that they're seen as attempts to pretend all that bad press doesn't matter. Hence the clockwork negative reactions--the same way the good news stories are lost in the greater malaise about the world.
