Razib Khan Aug 2023 blog post- People In Brazil Are Quite “Mixed-Race”

[Sephesakueu]

The Brazilian core of the Ancient Brazilian Colonial Nobility was Portuguese, Catholic, Big Landholder, Slaveholder and member of the Government/State. Brazil became the center of the Portuguese Empire in 1808 when the Portuguese Royal Family moved to Rio de Janeiro, the new capital of the Portuguese Empire in the Napoleonic Wars.
Protestants and Jews were not considered "White" ("Brancos") in Brazil because they could not marry in the Traditional Catholic Church - "A Santa Madre A Igreja Católica" - The "Original" Roman Empire Catholic Church !
Razib Khan is considered Black in Brazil because he is quite pigmented in terms of phenotype.

Protestants in Brazil in colonial times were aways of north european stock , that is they were perceived as actually whiter than the colonial white elite, even by this racial-economic elite itself, because pygmentation wise they almost aways were.
The thing is that before the scientificism of superior and degenerated races of the 19 th century this brazilian elite did not care much to being perceived as inferior to the anglos, after it, they decided to for real call a bunch of germanic immigrants to mix itself with and "improve" its racial character in the eyes of the european empirialists.

Second non sense thing you typed  Razib Khan has quite caucasian features and straight hair , he is also not that dark . Nowhere in Brazil he would be perceived as black , more likely as a light pardo or  as you typed yourself he being also of good social status and wealth it would even be more likely for him to be  perceived by many as "socially white" almost in the same level that some well off middle eastener groups are in Brazil.
