Final answer:
The provided text excerpts do not mention a character named Monte or his diagnosis from 'When They Call You a Terrorist: A Black Lives Matter Memoir', hence an accurate answer to the question cannot be deduced without further context from the book.
Step-by-step explanation:
The subject of the question relates to specifics of the book 'When They Call You a Terrorist: A Black Lives Matter Memoir' by Patrisse Khan-Cullors and Asha Bandele and why 'Monte' was eventually diagnosed. Unfortunately, without additional context, it is challenging to provide an accurate answer about the diagnosis of 'Monte' as the provided text excerpts do not mention a character by that name or a diagnosis. These excerpts mainly discuss systemic racism, the Black Lives Matter movement, and associated events, and do not appear to directly answer the question posed. To provide an accurate response, more information from the book is needed regarding Monte's character and his diagnosis.
