It could be argued that it's just a question of which and how many gaps the God is stuck in.
I.D.ers seem to need to point to what they consider to be evidence of their designer, whereas those who stick their Gods in more remote gaps seem to be more in favour of the idea that faith is required in order to believe in their deities, rather than evidence. But there's no clear dividing line.
This is a good topic title, certainly, and you have a strong argument, randman, if you're claiming that "theistic evos" are, in a sense, I.D.ers.
