Probably true but the extent is debatable. Would conservative scientist let that one issue cause them to aid scientist who believe in global warming, or are many of them among that group? Would conservative scientists ally themselves with a party, the Democrats, who openly aids the terrorists against this country? As scientist, do they see a fetus as simply a mass of cells with no worth?
There are a lot of scientists and other highly intelligent fellows...
I assume you include yourself among those.
...who lean conservative but would never think of voting Republican, just because the party is perceived as being anti-science as a result of the creationist presence.
I think you have it logically backward. It is much more likely that being strongly pro-science would make one anti-creationist rather than vice versa. I know of no creationists who are anti-science. Anti-evolution doesn't mean anti-science. In fact most religious people are not against evolution as a possible way for species to develop. They are just against it as a replacement for creation.
Since there are many religious scientists and many religious people who appreciate and admire science, I find your argument to be either ill informed or disingenuous. You don't seem ill informed but perhaps you are misreading your fellow scientists.
Anti-evolution doesn't mean anti-science.
Yes it does, when "anti-evolution" means ignoring or denying the physical evidence for evolution, or dumbing down the scientific meaning of words to make them conform to PC.
