Sorta hard to win the “apologetics war” when Christians come armed with reason and doctrine and Moslems come to the discussion with AK-47s and swords offering the discussion point of “Convert or die.” and if you don’t do the former, they will immediately make the Christian a martyr.
Islam is a heresy which rejects God’s Gift; Free Will. Man once aware of the truth of God and rejects God. In both the old and new testaments for not doing so the punishment is left up to God to decide, not man.
