I agree. Indeed, I'm surprised there's any question.
There's a lot of obvious humor. The t-shirt/underwear ad on the right-hand side of the page catches my eye right away.
And there are plenty of over-the-top posts which also seem pretty blatant tip-offs. It doesn't take much looking to find them. I clicked on the archives for January 2008, the claimed starting month, and quickly saw enough to convince me.
For example, the second entry on the site (from January 2008) is
"Proof Creationism is Real, Evolution False!" The proof: two pieces of toast, one with what looks like the common conception of Jesus and one which looks to me like Madonna.
Not the madonna of Bible stories. Madonna, the modern singer.
The entry right below it is "Hookers for Jesus". Also seems like pretty obvious humor.
Another one that grabbed my eye is
"Soccer is Gay". Again, obvious.
But quite apart from obvious humor, there's another tip-off that the people behind this site are not who they pretend to be. Click on
"Should Atheism Be Illegal", one of the items which is less obvious in its humor.
This appears to me to be an attempt by an atheist to write something resembling what they imagine an atheist-hating religious nut might write and which is intended to be only slightly over-the-top. Still, I'm surprised anyone would take this at face value. The alleged quote from George Bush gives it away.
"I don't know that Atheists should be considered as citizens, nor should they be considered patriots. This is one nation under God." - President George W. Bush
This is something which some atheists believe Bush said (based on the recollection of atheist Robert Sherman of an encounter he had with Bush). But it's something which, from what I can see, anti-atheists deny the authenticity of.
It is possible Sherman's recounting of Bush's words is accurate, but this has never been confirmed. As such, it has been a point of contention. Some atheists use this as an example of the prejudice and discrimination which exists against atheists.
Now, I haven't browsed a whole lot of anti-atheist sites to confirm that. But I would be very surprised if there are any genuine fundamentalist sites which use this alleged quotation and believe it to be genuine. (They might agree with the sentiment; but I doubt they acknowledge it as an authentic statement by Bush.) To me, its presence on the site is a pretty good indicator this site was written by atheists rather than atheist-haters.
