Oh, so you don\'t approve of beastiality. Good. It\'s sad that this is the main reason a lot of people won\'t let two people in love get "married".
Definitions change all the time, it\'s time to update our definition for marriage to allow gays to be married. It happened already. 18,000 people in Cali are "gay married" and no one has even tried to elope with a giraffe. Don\'t be silly.
Besides, if you want to go down that slippery slope, a pet can\'t be consenting so it\'s animal abuse and not allowed. End of debate. The arguement for polygamy is a better one, and I don\'t know enough about it to say anything one way or the other.
Essentially I agree with you about civil unions, but call them state marriages or something even across the board whether you\'re straight or gay. Then if a church wants to recognize your marriage, let it.
