Most of the laws of man are based on interpretation of the bible. Use homosexual marriages as an example. If two homosexuals are married according to the law, then who are they hurting? They aren't raping people or being whores. Who are the victims of this crime of marriage? Who are the victims of homosexual acts?
Exactly, the laws ARE biblical, and I'm thankful for that. Look at the perversions of men like the wacko in N. Korea and Hitler. Do you not know what they do/did?
As far as marriage and homosexuals go, I have no problem with them being kechua or together. What I do have a problem with is that they (and you) seem to want to use the sanctity of marriage to their own advantage, but yet they don't follow the principal of mariage in that it is supposed to be between a man and a woman. Why is it ok for someone to believe in something biblical like marriage, and yet NOT believe in the Bible itself and it's teachings? That's a bit hypocritical don't you think?
As far as who homosexual marriages hurt, all I can say is that it could possible hurt the chances of survival of our race/species. If everone chooses to be homosexual then what happens to reproduction? Now, in our times its not fathomable, but think about the long term big picture and how many generations would fall away if 1/10 start off kechua, then it doubles, and triples, etc...over time what could happen to us?
