It is not right for me or you to dictate what others should obey.
Man can make their own common laws to protect basic human rights, commerce, environment and in any areas we feel could improve our lives.
But we should not make laws based on our religious view points on others who do not share our religious view point.
This is why our early founding fathers decided that there should be a separation between the Church and State. I even feel this action was inspired by God.
I do not want a Muslim to dictate to me that I should stone a woman to death. I don't want a Christian to dictate to me about gay marriage. I don't want a Hindu to dictate to me how I should treat the lower caste.
We as humans write our rules as we see fit. God is very capable of taking care of his rules, if any, without the help from any one of us. I honestly believe that God gives us free choice.
