The main reason why Atheism defeated Christianity in America is that Christianity is divided into thousands of denominations but Atheism is united as one philosophy. All atheists share one common goal, to eradicate all Christian forms of religious worship and the moral codes associated with them.
Atheism owes its success to its lack of discrimination between the sects of Christianity and all major churches. Atheists maintain good relations with the leadership of the dominant American faiths and even act as their advisers. Therefore, in American sectarian colleges and universities, for example, one will find many professors and instructors who are atheists.
Atheism appeals also to the feminists, homosexuals and leftists, because it allows them to reject the moral code inherent in the Scriptures and all its interpretations. Atheism has been systematically destroying American values since the early part of the 20th Century. However, Atheism did not gain momentum until the Depression. The Depression proved to most Americans that Christianity was a bogus religion that could not protect its members against economic disasters and starvation. Thus when a new religion emerged in America after the Depression, which adopted the Good Times preaching theology, Atheism began to make inroads into the mainstream American Culture. Atheists could easily see that the Good Times preaching was aimed at fleecing the public, as the main doctrines of Christianity were abandoned by the pastors and ministers of the even mainstream American churches.
At first Christianity flourished after President Franklin Delano Roosevelt instituted Social Security and fought off the Nazi menace. However, as the Atheists took control of US politics and the educational system, it was only a matter of time when the greed of the various churches would divide the churches in their competition for money.
The Atheists' finest hour in their victory over American Christianity was the Scopes Trial in 1925, also known as the Monkey Trial, the result of which was that the Supreme Court made it unlawful, in any state-funded educational institution, to teach the story of Creation and mandated the schools to teach instead that man was descended from apes.
However, the Atheists' final blow against American Christianity came in the early 1960s, when they successfully argued that the freedom of religion of one boy in primary school was violated by the prayer at the first period of classes, which all the schools in America had practiced since America was discovered.
This one reversal of the US Constitution opened the floodgates that demolished the Christian Spirit among the majority of the future generations of Americans. Today, after seven decades since Atheists began a relentless campaign against American Christianity, we have finally come down to this one election where the defeat of American Christianity is finally at hand.
Whatever happens now will be God’s Will. Nevertheless, the future of the United States of America will be uncertain with the election of the first Atheist American President, whoever that may be.
