Then I would say no, they are not Christians. For example Mormons, they might claim to be Christian, but I would say they are not.
So I see your point. But even people who pass the key test of being a Christian, can believe and practice horrible heresies.
So just because someone substitutes Dogma for Scientific objectivity, doesn't make them a non-scientist. Same thing with global warming.
I don't intend to judge individual scientists any more than I would judge the vast majority of Christians. Even if they believed a doctrine contrary to traditional Christianity, unless it was one of the two key ones, I'd give them the benefit of the doubt that they are Christian. Likewise, I won't call a credentialed scientist who claims to believe global warming, a non-scientist. I'll call them wrong. I might call them politically motivated on this single issue.
I also might very well accept a person as being Christian. But that doesn't mean I will accept everything they say as being the truth. Or assume that they are right about everything. Likewise being a scientist doesn't mean everything they say is based in science or even said with integrity.
So you divide them into Useful Idiots, despicable whores, and SINOs.
