Let's take a moment to think about why the United States was founded. Back in the 1500s and 1600s, Puritans and Pilgrims were exiled from European countries for not following the religion set by the monarchy. When the U.S. Constitution was written, the first amendment protected the right of religious freedom and the separation of church and state, making this law unconstitutional.
As the United States we're supposidly founded and based on freedom, that can not be held with forced religion and religious views. As a Democracy that has been nicknamed the "melting pot of the world", the U.S. Was built on worldly customs and not just exclusive to Christianity. Christians should know that church and state are meant to be kept seperate, and U.S. Citizens should KNOW what the Bill Of Rights states. "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof"
We should not use the law to enforce Christianity or any religion for that matter. America was founded on the important principal that Americans may choose which ever religion they want to worship and using the law to enforce adherence to one particular religion goes against what this country was founded on in the first place.
A major contributing factor to the success of america was the clear separation of church and state in the constitution. "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof..." Why should we make such a drastic contradiction of the First Amendment if it worked so well so far, why should we start to promote non-equality of religions?
One of the fundamental laws of this country is freedom of religion and the ability to choose which religion one closely associates with. Creating a law that enforces Christianity upon a nation's fellow citizens is an affront to this law and such should not be enforced. Human beings have the right to choose what they want to believe in, regardless of religion it is.
