I argued the degree of difference did not matter, because it was in the same ballpark as other types of already available materials.
That the difference didn’t matter is my opinion and that is just disagreement. Determining what ballpark something is in wrt damage is, in our context, subjective, no? I did not think what you argued (or what I thought you argued) was impossible or unimaginable. That is different from incredulity. Right? I don’t care either way, honestly curious. You may enlighten me if you wish.
It seems silly to be able to say to everyone that disagrees on an assumption you made that they are making an argument from incredulity.
