Someone probably would've said the same thing to Galileo or Copernicus, I'm sure.
Galileo and Copernicus charged the general public for glitzy Power Point displays? LOL
Someone did. The difference was that those guys had the "mickey". They had theories that actually worked, that proved productive in advancing scientific knowledge. (Galileo, at least. Copernicus' advocacy of heliocentrism was pretty vague on the specifics, but later elaborated by others.)
Heck, IDers don't even have a theory yet. And since they refuse, in principle, to consider, even speculatively, any question of mode or mechanism (i.e. how, when, where or in what specific forms "design" is actually instantiated) there is no foreseeable prospect that they ever will have a theory.
