Everything in the article has something to do with the Indigenous people of Brazil, but that doesn’t mean all is relevant useful information for the sole Wiki page. Some of the stuff is important to the page but should be more explained on a separate page with a hyperlink and not take up too much space. Upfront the article has no biases, some may say it does if they are looking through a very euro-centric lense. There are no claims or frames that would shift the article to one way or another. The article does an okay enough job of describing what actually happened to the Native population of Brazil. No viewpoint is over or under-represented in the history. However, the contemporary Indigenous movement is extremely underrepresented. That is odd considering that the history of the Natives People is a huge part of the page (something that is said they do not know a lot about) and not something that is so easily accessible in this day and age.
The citations and links look extremely credible. Many of them go towards official government websites, scholarly books, and credible news sites. From what I can tell, most of the sites do not support or bash the article but simply provide information. As far as I can see every fact is paired with a reputable reference. The news sites are traditionally seen is unbiased, but are very centered around white people. Many people will not note this bias in many news outlets. The information seems up to date. There definitely needs to be more added to the contemporary section or a whole new page created for it.
There are many conversations on the talk page. Many other Wiki users have been conversing about changing the name to include “in” and how previous contributors have some gross prejudice towards Native People. The article is a part of the WikiProject Indigenous peoples of the Americas and WikiProject Brazil. It has an overall C rating. We discuss this topic in a much more intersectional way.
