You either accept that method or you don't, you can't pick and choose.To choose science for one specialty but pseudo science or dogma for another is inconsistent.
Yes you can (edit for clarity: Yes you can use dogma for one domain and science for another). It is perfectly consistent to say that the word of god is the ultimate truth but where god is silent on an issue science is the next best thing. There is no a priori reason to claim that the scientific method will give more accurate results than the word of god. The fact that science needs to keep updating itself is, for some (most?) people evidence enough that it can't be as accurate as the word of god.
But, thats not my point.
Most people get whatever knowledge they have of science from sources several level removed from the scientist. As a result, they don't get access to see the true science. Instead, they take what they hear from (seemingly) credible sources and trust it. Maybe they put some thought into the arguments given but generally they don't, especially if no one is disputing what they hear.
With evolution though, there's people yelling at them from both sides. Both sides use what seem to be logical sounding arguments (though, under close inspection, one side's logic breaks down). In addition, one side also claims to represent god, which they are told is the ultimate truth. In their minds therefore it becomes:
Science vs Science + Ultimate Truth
It doesn't take a genius to see which side would win in that battle.
However, with medicine, God appears to be essentially silent on the matter. There are no options to weight. Everyone agrees. Nice and simple.
So yes, there is some hypocrisy, but its limited to the politically motivated few who are pushing the ID agenda. The masses are not guilty of true hypocrisy.
