I agree with you that it's not inherently about an Abrahamic god, but when you see people quoting Richard Dawkins and The God Delusion, it's pretty obvious where it's going.
That being said, I'm a Christian. So there's obviously a bias I have towards it. But I still understand that there are massive flaws with the mythology, and it's essentially why I disregard the entire Old Testament as nothing other than Jewish myths handed down and random history bits during the time of the split Kingdoms of Israel and Judea.
Being critical of that is fine, as is being critical of the shit that has happened in the name of religion over the last... Thousands of years. Hell, I'm critical of those same things.
It just sucks that I come to this forum because I'm looking for tolerant conversation, and it seems like every single week, without fail, there's a thread just like this. And it turns into a giant circle jerk. Being critical and belittling someone for believing something isn't the same, however, and doesn't make for a positive conversation from the outset.
