Kudos to Joel for saying homosexuality is a sin, but, like a pilot or a sea captain, if your coordinate system is off by even a tiny bit, your destination will be missed by a heckuva lot.
Toward the middle of this clip Joel begins to lose a biblically-centered navigation system when he concedes: "I'm not against anything." He and his wife Victoria also confess that they would attend a homosexual marriage; and therefore, be witness to, not speak out in objection to, and have to "forever hold their peace" about that union.
Sadly, Piers Morgan probably categorizes Osteen as one of those right-wing conservative, Christian, Republicans. He is incapable of distinguishing between an Osteen and a Mohler, MacArthur, or a Piper. To his credit, Larry King did see these distinctions and had these Biblically-sound pastors on his show regularly.
