"what specific indisputable adverse consequences to society do opponents predict to occur? "
1) Can two gay brothers marry?
2) Gays would then have the same priority for adoptions. Does anyone in their right mind think Rosie O'Donald is an acceptable parent?
3) Many increased costs to insurance and retirement funds.
4) Gays in military - no ask no tell would eventually collapse. Could two gay soldiers in the same unit be married?
5) Can a father marry his son? No offspring would result, after all.
6) If marriage is not defined as between a male and female, what about with your favorite monkey?
The results of legalization are in the long term very disruptive.
Coyote:
Are your questions meant to be examples of what you predict will happen once same-sex marriage is legalized?
OK--let's assume you are correct. Now, please explain the likely consequence to society.
GAY BROTHERS: How many gay brothers do you suppose there are in our country? If they ALL decided to marry, what adverse consequence do you anticipate occurring?
ADOPTIONS: If a gay couple provides a loving, caring, nurturing home -- why is that a problem for you?
INSURANCE and RETIREMENT: Won't the gay enrollee pay the same premium or costs involved as a straight enrollee?
MILITARY: If your hypothetical two gay soldiers married, why would their marriage be more troublesome than a straight couple in the military who marry?
MONKEY: Any monkey you know asking to marry a human or vice versa?
