Proposition 8 Upheld?!? What were they thinking?

Vote: The instrument and symbol of a freeman's power to make a fool of himself and a wreck of his country. Ambrose Bierce
Today we heard that California Supreme Court agreed that Proposition 8 would be upheld.
It was a sad day. I get so angry about the injustice that people choose to support. Proposition 8 was passed back in November and was being reviewed by the California Supreme Court to decide if it would stand. Of course the narrow minded, dye in the wool religious hypocrites voted for this proposition and it was passed.
The California Supreme Court did not do its job and rule that this was unconstitutional. Instead they upheld this terribly bigoted law and once again showed the world that we do not live by the standards that we say that we live by.
I am a strong Christian and I am so embarrassed by the people who are claiming to be a Christian and be so judgmental. I am not sure if I believe that being Gay or Lesbian is a sin or not. I have done research on the subject from the Bible and have not seen anything that says that Sodom and Gomorrah was burnt because people were gay, I believe that it was due to the fact that the entire city was sexually corrupt. They were banging down a door trying to get the angels to rape them, which in no way does that prove that it was because they were gay.
I also believe that any sin is on the same level, for example; lying, killing, stealing, cheating, and coveting you neighbor’s things. We have no laws about lying and cheating. We encourage people to want things that other people have. Obviously there are laws about killing people. These things are all weighed differently in the land of people but to God a sin is a sin. Everything can be forgiven and he does not rate his sins from best sin to worst sin. He forgives anyone that will ask for the forgiveness. We as humans however do not punish people for lying the same as we punish people for killing.
The beliefs that I have as a Christian should be affecting only my decisions not the decisions of people who are not religious. We claim to have a separation between church and state and yet there is no separation. We do not live by the Constitution of the United States but allow this flawed system of voting. We vote based on few facts that we know, the skewed advertisements of supporters and opposition, and we even just make decisions on a name that we like. Many people are uninformed and emotional voters that allow other things like religion bias their vote.
There have been far too many groups of people that are treated unfairly and not given the same laws based on color of their skin, religion and sex. We are so proud that women got the vote. We cannot fathom discriminating people based on their race. We allow all people of any religious background to have freedom. And now we need to allow people who are Gay and Lesbians to have these same rights of everyone else.
