Is this a good theisis statement for 'To Kill a mockingbird' ?!?

The book was made in the 60's to further give voice to the civil rights movement, because of the then current "equal, but not equal" treatment of blacks back then. It was the first book and film to depict a black man as being innocent and inspired sympathy for the black community and the unjust treatment they indured through those years and the preceding years. It was more then just an "Innocent man" it was emphisised as an "Innocent black man." There were other aspects of the book/film that were revolutionary during that decade including writing about , domestic violence, and profanity. Of course these things had been done well before then (Shakeshpere) but they were definitely not popular subjects to put in a book/film. I would definitely change "innocent people" to "an innocent black man."
