Child molesters, prostitutes, animal torturers, fornicators, drunkards, and witch doctors often act together with other consenting adults in their chosen activity. That doesn't make it right or acceptable. It's even conceivable for consenting adults to freely break every one of the Ten Commandments. This is a commandment of political correctness and not of Christianity. Christians are commanded to love God and neighbor.
True love includes charitably pointing out errors that lead to destruction.
Although it's not politically correct to say so, Jesus plainly taught there is a judgment and there is a Hell. It's wrong to approve of immoral behavior and even worse to approve of it in the name of Christianity. There appears to be great confusion about the Bass affair and Kathleen Lamprecht's letter. Mrs. Lamprecht doesn't condone what Ms. Cupp did to Ms. Bass. She is merely stating that when you live against God's law and, for that matter, nature's law, you put yourself in a compromising position.
