We need to note again that most Christian denominations accept the idea of theistic evolution. So people who post here in opposition to anti-evolutionists, are not necessarily anti-Christian.
Indeed, I'm certain that Jim Robinson does not require posters to be Christians. What he does expect is that we will treat each other with at least some degree of respect, deference and, well, let's say good humor. ;-)
We need to note again the appeal to the fallacy of popular opinion.
So people who post here in support of evolution, while claiming Christ, must necessarily adopt the same fallacious lines of thought and place a higher value on the opinions of unbelievers to support their position.
