What can be done to help the Creationists?
Well, first of all, I think this is part of the problem. We are often accustomed to grouping people in one lump based on their beliefs. We have a tendency, even if we don't intend it, to indict everyone.
We all should probable be more cautious in our dealings with one another.
Rather than blame all creationists for the tactics you posted, perhaps we should deal with people on an individual level. Certainly not all creationists are as fanatical as others, just like all evolutionists aren't like Dawkins.
So perhaps its unfair to make sweeping allegations. Why not just deal with the argument they are presenting. If it is as transparently weak as you claim, the it should be no trouble dismantling a strawman, right? And if someone acts pigheaded and resorts to ad hom, then we should deal with that on an individual basis, no?
Afterall, isn't
this how racism, sexism, ageism, and all of the other
ism schisms begin to flourish in the first place?
