Now I'm confused... How would bad publicity in the church ultimately deny your brother the same agency you have? I understand the argument about bad publicity, but in the Church's case, 2 facts are true: (well, at least 2)
Whether it be Prop #8 or Prop #2, it is still politics. I like to have my own standards as set by the Church. That is my free agency. I also like to be joyous as spoken about by Joseph Smith. As my brother's keeper can I deny him the same?
1) There has always been plenty of bad publicity for the Church. Hasn't stopped its rapid growth.
2) Any publicity in the end is 'good' publicity in that any fair-minded person following the Light of Christ who is introduced to the Church- in any fashion- will eventually join it (whether it be in 5, 10, or 500 years).
Ultimately, the bad publicity is an unfortunate side effect of living in a fallen world. When God's people move in a direction ordained by God when the world is moving the opposite direction, people of the world decry the people of God.
If you were talking about Prop #8 supposedly denying your brother the same rights you enjoy... let's not get into that here. I agree to disagree to whatever.
