IMHO specification of Marriage between only 1 Man and 1 Woman should not have to be spelled out. Unfortunately, due to the unlawful actions in San Francisco, our Government's system of checks and balances are slipping into choas. Not surprisingly, Bush has no choice but to voice concern and direction regarding an issue resulting from people making a decision to oppose the populous. Why are they in defiance and feel it necessary to validate their unions? So that they don't have to feel bad, in a vainly futile attempt for the purpose of feeling good about themselves from their choice to relate sexually with those of same gender as themselves. And because, it is a ultimately a choice they have made to live a homosexual lifestyle, discrimination is not applicable!
It's like someone who chooses to shoot someone else and cries "Discimination!" because they feel their civil rights have been violated by removing their freedom of choice to shoot someone else when they are thrown in prison!
Obviously, the law is the law. When someone violates the law there must be consequences. It is up to our government to uphold the law, not change it to accommodate those who would create anarchy.
