Why “supposed Christians”? Jesus clearly told the men stoning the woman caught in adultery not to condemn her unless they were free from sin themselves. However, he told her to sin no more, meaning he did not condone the behavior. It is not hypocritical to condemn Fluke’s behavior, or even label it for what it is. It it would be wrong for a Christian to personally judge.
I agree with what you say but my point is Rush called her a slut (which I agree she is, by the way) but name calling is just as sinful as what Ms. Fluke did and will most likely continue to do. The right thing to do is apologize for the personal assault. This doesn’t in any way ignore the behavior, just forgiving the sinner.
