What is your standard for determining when guilt by association is fallacious? How do you justify your standard?
Just like considering any other informal fallacy. Take the appeal to authority, for example. Is it always fallacious appeal to authority? Heck, no. That's why we have experts. It's only fallacious when we refer to an improper authority like referring to the local pastor on the latest scientific discoveries.
In other words, use your common sense.
Guilt by association is not always a fallacy. Prominent IDists have repeatedly admitted that they think it's silly to think the IDer is something like alien or Buddha. And yet they have also repeatedly admitted that they believe the IDer is the judeo-christian god.
Have you even heard of Cdesign Proponentsists? Have you even considered the fact that IDists seem more busy with advertising ID rather than perform honest-to-god real scientific experiments? When was the last time they even published a real scientific paper on ID?
The totality of the evidences point to a very clear motivation behind the ID movement.
On the other hand, the idea that the theory of evolution somehow supports a judeo-christian theology is a dead-end idea. There's no motivation for religionists to advocate the theory of evolution for religious reasons.
Again, if you want to use logical fallacies, make sure you know how to use them first. Take a logic class or something. Simply looking them up on the internet ain't gonna do it. When we're talking about informal logic, statements are fallacious only when they are. Not every 'no true scotsman' is a fallacy. Not every 'appeal to authority' is a fallacy. You have to look at the argument and decide on an individual basis.

I'm not going to repeat everything Percy has already said. I think Percy has given enough evidence to link ID with creationism. Guilt by association in this case is not fallacious.
