You should only debate Muslims (imo) to see if they can provide a reasonable response to your objections, and then let the readers decide who sounds more reasonable.
Many ignorant Christians will poorly quote the Qur’an out of context and look foolish, but there are questions we can ask that Muslims can’t answer.
The Qur’an is very ambiguous about certain characters and no doubt it says you may strike your wives if they are disobedient. Now, some aplogists may say that she has to be really really bad to strike her, and you can only strike her lightly; like with a toothbrush.
Now, does that explanation strike you as a solid one by being just a random reader?
Also, why did the Jews want to kill Jesus if He was simply preaching Monotheism to the Jews. Is there any history as to why they tried to crucify Him? Why does the Qur’an say the Disciples of Jesus who believed His message became dominant when we know that Christianity became dominant?
Now, someone could try to explain away these objections as best as they can, but from a non-bias onlooker there’s not one good answer. I could always provide more; just keep in mind that Islam ignores history and we know for certain that Jesus most certainly did die on that cross. If every historian can admit this simple fact about Jesus even while not believing anything else about Him, then why do Muslims not believe it? Well, the text says Allah made it appear that way, thus starting the largest Religion in the world.
