I assumed that everyone assuming that was correct, but it was odd because nothing the man says or does in the video identifies him as such. He doesn’t mention God or the Bible or in any way identify himself as a religious person. There’s nothing sectarian in the video at all.

So why did everyone assume that this man was an evangelical Christian?

Because he’s anti-gay.

...

Please let that sink in. Please contemplate what that means for the witness of evangelical Christians in America in 2012. Please consider what that means for the reputation of the church.

...

That video? This is who we are now in the eyes of the world. And they are not wrong to see us this way.

Oh, and as for that assumption that everyone was making the other day, that this goofball with the flaming Cheerios must be some sort of evangelical Christian?

Everyone was right.
