Your example, regarding stem cell research, ought to tell you something, but apparently doesn't. The only thing that stops creationists from eliminating vast fields of biological study is their lack of political power. For an example of how creationists behaved when they had political power, see the Trial of Galileo.
So, you approve of stem cell research of humans? From the 2nd trimester fetus, zygote, and all steps in between?
And so what about the Trial of Galileo?
This was performed before simple things like "innocent until proven guilty" came about.
Talking about the judgement of someone so long ago is foolish. Especially if it's your only example.
Why don't we modernize that a bit, Eh? How about the 1930's in Europe. Evolutionary theory has been around for a while by then. As a matter of fact, many politcal parties adopted it as part of their platforms. Can you think of any of them? I sure can.
Or even a step away from evolution: secular thought and reasoning. Hmm, yup, got another party just east of that first one that came to mind.
