You blaspheme, therefore you believe.
I was watching a Youtube video featuring some old Christian guy talking about the psychological commonalities of atheists and the Blasphemy Challenge-- I don't remember his name.
In response to the Blasphemy Challenge, he says that people do it because it seems dangerous, and it only seems dangerous because we know it's dangerous (to challenge God to strike us down and sent calamities). We know that it's dangerous because, deep down, we know God exists. Therefore, the atheist says, "I don't believe in God... and I hate him."
So, if I blaspheme against Zeus on Youtube, and challenge him to strike me down with a lightning bolt, that means I know Zeus exists as well.
I need to set up a Youtube account and issue the second blasphemy challenge (Deity Showdown). It would include a clip of the guy saying that because we blaspheme, we know God exists; so, we must then acknowledge that we, as atheists, are capable of calling all gods into existance by blaspheming them.
So here's the plan: we blaspheme all the gods we can think of, meaning they all exist, and then we watch them fight to see who can smite who first.
