Very important author that I want to recommend: Saad D Abulhab.
He primarily deals with orientalist myths regarding the Arabic language and Arab history, but it has obviously significant impact on their bizarre claims against Islam(especially the Quran) as well.
Here's articles and excerpts from his books:

It's eye opening how accepted their lies have become. And it makes you realize that if they can't even do justice to the Arabic LANGUAGE, then how possibly to Islam? If only the apostates from the Arab world that blindly accept western "scholarship" could take heed.
