Yeah, he can manage the following:
invalid and irrelevant
valid and irrelevant
invalid and relevant
Its just the remaining possibility (as you've pointed out) that proves out of his reach. ;)
Standing up for RaceBannon for just a moment--not all of his cut'n'paste about Newton was both invalid and irrelevant.
And he did have a valid point (for someone not versed in the sciences) about different forms of evolutionary theory.
To someone who hasn't had scientific training, and who is unaware of the progression of models / theories / whatnots, it *could* very well look confusing.
OTOH, given the number of links sent to him, he cannot necessarily plead ignorance in good faith any longer--unless he just got overwhelmed and didn't have time to investigate and digest the links given to him.
(But you know, he's been on a number of these threads for *months*, and has found time to search, cut'n'paste, and post regularly, so I dunno...)
Cheers!
