Polygamy in no way, shape or form legal in this country. Only the original marriage is recognized from a legal stand point. So they would not reap any of the benefits under the law, i.e. survivor's benefits etc. As for same sex marriages, morally this atrocious and against God's teachings. I believe this country has taken a huge step backward in allowing this in some states. Since the BSA is a private organization, they have every right to refuse membership and/or revoke membership regarding anyone in these situations as well as atheists. The BSA was founded on the principles of God and his teachings. I'm trying to keep the use of the word God in the general sense, since there are multiple religions. If I offended anybody, I apologize, that was not my intent. I only wanted to shed light on this topic from a legal standpoint.
