street epistemology

[Delicate]

You've pretty much conceded my point.

Atheists claiming lack of evidence for God might well be like blind people who claim lack of evidence for color.

I wasn't going to respond any more, but this is just absurd.  I work at a blind school.  1) In case you didn't know, the vast majority of people who are blind have some usable vision - - 85% - - and they react to light.  When that light is at the right frequency and spectrum, they can see color.  2) For those few who live in total darkness, we teach them about the spectrum of light pretty much the same way as we do sighted students: we describe frequencies and wavelengths.  Color, for them, is a mathematical equation, which we also demonstrate by correlating the light frequencies to sound waves.  There are also the descriptions of color given by their peers - red is "hot", blue is "watery and cool", green is like grass and leaves, yellow the feel of sunlight on your face.  These add some emotional value, perhaps - it's camaraderie.

That's interesting. It must be quite fulfilling to work with them.

But pertinent to our discussion, what seems to be happening is that you teach them, and they believe (at least the ones with total darkness do) without having access to the empirical evidence. 

What if they had a standard of evidence that said "I only believe what I can empirically verify"? In that case they would have no grounds to believe you. For them, the belief in color would have to be taken on faith.
