The very first sentence of the very first right guaranteed to the American people is the separation of church and state. But this is what I see happening: People believe in religions. Religions dictate morals. People vote based on those morals. Religious ideas enter the political sphere through the voting process. Laws and policies are determined or otherwise influenced by those religious ideas. Church enters state.
Let’s take gay marriage as an example. On what basis can anyone claim that gay marriage is wrong outside of a religious context? The ‘immorality’ of homosexuality is only ever justified by the interpretations of scripture. Without religion, no argument can be made against gay marriage. [See comments]
