He is right you are just stubborn - you don't think it's even possible that you are wrong so you refuse to examine fairly.Majority of ex muslim are jaahils just like you if they knew the right creed they wouldn't have left and alhamdulilah when murtad reverts back to Islam they follow the minhaj which Ahlu Sunnah wa Jam'aa.
Since you're jaahil the salafi movement in Arabia started by Abdulwahab initiated programs of settling bedouins in villages and teaching them the religion since so many of the nomads back then then didn't know the religion very well
The reason why people have been running circles around your arguments is because quite of lot are quite familiar with Salafi ideologies. However, you have zero familiarity with Sunni thought besides the polemical texts your shaykhs write.
