The "we should not allow equal rights for poly because it would be complicated" argument.<quoted text>
I answered your question but I guess you have ADD
4. marriage above all else is a social contract. Inheritances, medical decisions, etc are all part of that contract. With polygamy, the lines of who gets what, who makes what decisions are blurred and lead to legal battles. Does one of the wives who is not the mother of one of the children in the marriage get to make medical decisions for that child is a prime example of why polygamy is illegal.
These are all rational, logical reasons why the slippery slope fallacy is moot. However, judging by your previous posts, intelligent logical debate is not your forte. Debating with a wall has better results.
same sex marriage and polygamy are two separate issues. and comparing them as equal is a fallacy..something you seem to use quite frequently.
as I said marriage is a social contract. Polygamy, besides a host of problems it raises, legal issues is the biggest.
Heard it. It's bogus. We can work it out. Complexity is no reason to deny equality.
