I'm a college math student, and I had the unpleasant experience of checking some data on what IBGE (gov statistics) called a "census", which usually isn't available to citizens. It was about a survey made 10 or so years ago, which I got from a highschool acquaintance in the same university, if I recall correctly, he asked a geography teacher for it (for a socioeconomic essay or some other commie "science") and apparently he had no trouble getting such documents. That, on its own, already show us how corrupt Brazilian government is, you can freely choose whatever truth you want to indoctrinate students with, as long as you have a leftard degree.
Well, to the point. I was mainly interested in the math subject, which was obviously quite straightforward. What really took my attention were the notes and some reports annexed to the documents, most clearing issues in some parentage relations with the subject's race. Obviously, they got to fix it with tumblr retards or when a nigger figures he was white all along, and so they cross with the parents info as proof (i.e parents are both white with blue eyes, but kid is gender: nigger), but that wasn't entirely the case, more often than not, they would also add socioeconomic information as supportive of the subject's race. It was sort of intriguing and disgusting to read such delusions, it ranged from obvious discrepancies to closely related people with the same heritage and characteristics being classified as different race. The case I remember best is of a family, mapped thoroughly, from a southern state (heavily colonized by euros), one of its branches (let's call it main branch) was entirely classified as white, most of its members had dark eyes and black curly hair, but what seemed to be "undeniable white skin", they were also rich and living in a nice part of town. Another document, dated a few weeks after, from the same idiot who mapped the main branch, had some quite interesting information, the subjects in this case were closely related to the main branch (cousin of the father of the main branch), a women with the same heritage as main branch's married a white man (with a even whiter heritage than the main branch, but not as rich), both their kids had dark eyes and curly dark hair, exactly as their mother, but the mope analyzing it thought different, in his words, although they had fair skin, the color of their eyes and hair, plus their economic situation (living in a rather bad place in town) made it clear that they were in fact not white, but pardos (monkeyspeak for mixed).
I obviously never took any racial statistics seriously in Brazil, as anyone with a brain would. The corruption, terrible logistics situation and the absurdly mixed population are enough to call any census as not accurate right beforehand, it still surprised me anyway. I always assumed they would have at least some basic common sense as to not rig it without even noticing. How do leftards do that without any notion and how the ridiculous amount of cases went completely unnoticed/forgotten in the system is beyond me. Honestly, at this point I'd assume the actual white population in this country to rage from 40 to 10%. It's a lesson to learn early if one lives in a shithole, to rely and trust in nothing at all.
