I was reading a Wikipedia article on Gentoo Penguin and came across the following Paragraph.
The application of Gentoo to the penguin is unclear. The Oxford English Dictionary notes that Gentoo used to be an Anglo-Indian term used as early as 1638 to distinguish Hindus in India from Muslims. The English term originated from the Portuguese gentio (compare "gentile"); in the 20th century the term came to be regarded as derogatory.
I am particularly interested to know why the Portuguese word gentio from which the English Term Gentoo originated is regarded as derogatory. In the similar context does the same English Term would also be regarded as derogatory similar to the root word?
Context We have named our baby "Gentoo" and now I have realized that the term may be pejorative.
