As one who had faced many engagements in this forum, it is my opinion that almost every theist uses the same arguments and thus fallacies. Personally call this “The Apologist Handbook”. From that expienrce I have accumulated a list of common fallacies they use.
You will learn them, you will also learn their counters.
What is important is that theists were taught their religion, they were also taught their arguments. The stories are finite, the arguments are finite.
If they actually began to examine their beliefs, then they are possibly starting down to the path to becoming atheists.
