Same sex marriage

This is a huge decision for our generation of people to make. It will change our society for ever. It will change how other countries view us. It will change so many things that I am glad that it is taking so long for it to be voted in/out. Has everyone thought about this?
We are a Biblical based country, whether you like it or not we are. It clearly states in the Bible that marriage is between a man and a woman and that same sex relationships are sinful. Same as sex before marriage, being too fat, getting drunk, I could go on and on. As we sit in our over extravigant houses(sinful), using way more resources than we need(sinful), we are stopping the gays from getting married? Do you see my conflict?
From what I learned from the Bible, our sin is the same in Gods eyes no matter what. Each sin we commit is like a brick, no ones bigger than the other. Although I may think I have a place in Heaven before a mass murderer, God does not. He sees us as equals.
As a mostly concervative lady I have a huge struggle with this. I do not beleive in Gay marriage. However I do not beleive I have the right to say that Gays can not get married. I do think same sex relationships are sinful, I have had sinful relationships, so I do not judge. I have friends that are in same sex relationships, and I would like to see some of them be able to get "married".
SO I can not say either way with complete 100% of myself if I think it should be leagalized or not.
One huge problem I do have, is this: Why can Pro Same Sex groups/persons post very nagative arguments, articles and statements towards people that do not believe, saying they are wrong and completely off the wall. Why are we not entitled to our opinion? Why should I be ashamed of having Biblical values. I am not causing harm to my gay friends, I do not sit in jugdement. Just because someone does not agree does not mean they are judging you. If they are who CARES!!! If they are judging you it's because that is their sin and they will have to answer to God for that themselves.
Is civil union not an option? I am not really sure the opinions of supporters/opposers on this. As far as Illinios goes I was just sent a letter by my husbands insurance company that anyone considered a partner is covered as a spouse. Marriage is not required, same sex didnt apply. You can get married in a Church and have the ceremony being same sex. For my husband and I it's not the state paper that makes us married, it's the vows we took before God and now the children we raise together. We are committed to each other, even though sometimes I would love to sufficate him in his sleep...thats a whole other blog though ;)
I guess what I would love to see is that Marriage does stay sacred, a man and woman and it not hurt anyones feelings, but I feel guilty even typing that. Guilt does not come from God I know this so it's not him putting doubt in my head. Are you going to judge me for having that beleif? If so you may need to look at why you feel the need to convince me or others. Is it because it really matters to you what we think? Do you really need our approval?
The fact of the matter is we are not all equal here on earth, the only place we are actually viewed as completely equal is in Gods eyes.
