Standing up for gay rights goes against what the Bible says. Homosexuals are not children of God and saying that they are is wrong.
Romans 8:13,14 (KJV) 13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live. 14 For as many as are led by the Spirit of God, they are the sons of God.
Romans 8:28 (KJV) 28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
