Typically, yes. People with extreme views typically don't fail to make inferences from their beliefs along the lines of "X is good, so doing Y, which creates even more of X's goodness, would be even better!" Y might in fact be utterly stupid and evil and wrong, and a moderate with less extreme views might be against it, but the moderate and the extremist might both agree with X, even though the failure of logic that leads the extremist to endorse the evil Y is the belief that X is good.
