Over the last few years 'The Church of the Flying Spaghetti Monster' has grown in popularity. Also known as Pastafarianism, this parody religion is a form of atheism that in reality is mocking Christianity.
The Church of FSM started as a protest against the teaching of Intelligent Design in schools - the reductio ad absurdum argument being that the FSM and 'Theory of Intelligent Falling' are just as scientific as the Theory of ID.
The reason I say that it is "atheism in full retreat" is because atheists don't actually believe in the Flying Spaghetti Monster (FSM). They think that belief in God is just as absurd as believing in the FSM, but the problem is that the FSM is not their justification for knowledge.
In debates between Christians and Atheists, atheists will often posit some hypothetical deity that they don't believe in such as the FSM, The Ghost That Never Lies, the Invisible Pink Unicorn, or other religions gods such as Allah, Krishna etc. The problem with this is that they are abandoning their atheism in order to defend it. As soon as the atheist does this the debate is over. They are showing that they cannot defend their atheism, and in order to try to defend it they are having to posit something they don't believe in.
Today on another post a commenter who I assume is an atheist, said that I should assume that they are a Christian. When I asked this person if they really are a Christian they would not answer the question. So I've refused to continue publishing that persons comments, because they are not being intellectually honest in terms of defending what they actually believe. The reason for this tactic from atheists is because atheism cannot provide a justification for knowledge or rationality. Without revelation from God they have no way of knowing anything for certain. They could be living in a world where everything is illusion for all they know.
In the debate between Sye and The Realistic Nihilist (TRN), Sye refused to debate TRN when he would not defend his actual position. For the purpose of the debate TRN wanted to temporarily adopt an evidentialist worldview. But this kind of jumping around between worldviews is absurd, and it's good for Christians to expose this absurdity and not let professed unbelievers get away with it.
In a different debate between Sye and a group of Atheists, Thunderf00t said that 'The Ghost That Never Lies' was his avenue to certain knowledge. When Sye asked him if he really believed that, Thunderf00t avoided the question.
As soon as atheists posit something they don't actually believe in, they are in full retreat. They've lost the debate right there, and as Christians it's our job to point this out to them.
