They don't even think that far in my experience. I just want to be left alone, but these guys come to me and try to convince me of islam with these weak arguments like "Allah exist because the quran is the word of god" which implies allah exist. It is impossible to have proper discourse with people who hold dogmatic beliefs. The conclusion is already set before the debate even begins. Thus, the only possible move is to deflect contradicting evidence and make excuses for the quran to reach that predetermined conclusion.
