Anti-religionists do not believe in god, and wish to attack ideas connected with religion whether they have anything to do with believing in god or not. Anti-religionists are therefore willing to dismiss ideas simply because of who presents them rather than on their merits, and are thus subject to a pervasive ad-hominem bias.
That if you had said that you are learning about "atheism" at the start of this subthread you could have avoided a lot of confusion and suggestions from people offering advice about books to read about religion.
