What is Reddit's opinion of Fidel: A Biography of Fidel Castro?

From 3.5 billion Reddit comments

We are talking about ancestry here. If that were relevant, then Fidel being born in Cuba would be enough. But it isn't. His mother's ancestry was 100% from the Canary Islands.

"Ángel took a wife in 1911, María Luisa Argota Reyes, with whom he had five children before separating. He then began a relationship with Lina Ruz González (1903–1963), a household servant of Canarian descent who was twenty-seven years his junior"

Complain about Wikipedia all you want, but the sources are there. For this particular bit it references the following biography:

Again, and if I have to repeat this over and over again, Fidel is from almost entirely Spanish ancestry with no Latino ancestry. The fact that his mother was born in Cuba is as irrelevant as Fidel being born there. His mother is of Canary Island ancestry and looks European as well.
