I think there is a big difference. Max Plank and others took their arguments to their fellow scientists. they published their results, they argued at meetings. The work was transparent and available for anyone to challenge. Most creationists (including Humphreys) don't make a legitimate attempt to legitimize their work. On a positive note, I did notice they presented at AGU. Comments from colleagues were less than positive regarding the work based on its shoddy science and not on his relationship to ICR. Let's see if he makes an attempt to publish in something other than the 'feel good' rags of ICR.
