Religion is currently intertwined within American government which should be prevented even in the simplest terms by the separation of church and state. The United States of America was intended to be a land of religious freedoms without the dominance of any specific religion. The lack of separation and the current christian dominance could be very detrimental to American society. The topic of Marriage Equality should not even be up for debate due to the fact that the main argument against it is religiously based. Any couple if they so choose, should be allowed to get married and receive all the benefits of that union. School programs such as sex education are suffering because of religious unease. Many schools are taught abstinence and that is it, teenagers should be learning abstinence as a valid option but the classroom should put heavy emphasis on safe sex and ways to prevent teen pregnancy which is a huge problem in America. While I agree that every person has the right to voice their opinions and that these may be swayed by religious viewpoints, religion should not be a factor in any politically argument. The emphasis currently placed on religion and Christianity in particular alienates entire groups of people within the country. In order for coherency within the country we need to learn how to distance ourselves from religion as it relates to government. If we do not then out judgement is forever clouded. Issues cannot be seen clearly if they are clouded by religious differences. Those who believe otherwise should be reminded that while it is perfectly within their rights to live their life guided by religious ideology they are not able to force others to do the same.
Unfortunately, if we are to adopt your perspective, in this day and age where the influence of the state pervades through every aspect of our society, what you are demanding is essentially compulsory atheism. Rather than the separation of church and state, what we need is the separation of state and society.
Religion is voluntary and it teaches us important moral lessons. Not to lie, not to steal, not to kill. These are valid lessons that everyone can agree with. Of course no one should be forced into a religion - and no one is - but we don't need to drive religion out of the public square. But what does the government teach us? The government teaches us that it's okay to lie, to rob and to murder. The government lies constantly. They steal constantly. Every dollar you pay in tax is a dollar the government stole from you. The government kills millions with it's wars, or cops just gunning people down in the street because "they thought they had a gun". Police routinely beat and harass people for no reason. They are violent thugs. Schools brainwash children. It's not religion we need to fear, with it's powerful moral lessons about right and wrong, it's the state, with it's violence, with it's dishonesty and with it's theft.
