I'm interested in Whistle Stop's "consenting adult" guideline for this question. Solely on that criteria (and allowing no other morale issues expression), should society forbid the following kinds of marriage? Please explain why. Note that a bad personal reaction to any of these examples is not sufficient to forbid the marriage. Remember what Amos said: "... your adolescent callow and calloused "Ewwwghhhhwww" response is inhumane, barbaric and ineffective."

1) Assuming consenting adults, marriages that would otherwise be considered incestuous (you pick the relationship).

2) Marriages involving more than two consenting adults.

3) Marriage involving an adult and a hat rack.

Remember that according to this theory, government is not to define what is marriage, only to assign rights and responsibilities within in it.
