As requested, responding to no-one in particular, but wearing my linguist hat for a while.
The word noob is derived from the word newbie, meaning “an inexperienced person”. This definition is actually given by some general-purpose English dictionaries, including the respected Oxford English Dictionary and Merriam-Webster.
However, these giants of English vocabulary are slow to respond to change, and few things change as quickly as internet slang. The word noob has in recent years accumulated significant negative connotations, implying that the person being called a noob is not only inexperienced, but slow (or unable) to learn, dull-witted and probably lacking in manners as well. More specialized online dictionaries, such as Netlingo.com and the Techopedia dictionary, support this interpretation and classify the word as derogatory.
So just like the Spanish word for “black” used to be a neutral term for a black person in English, very few linguists or cultural historians would claim that it doesn’t have negative connotations in modern speech.
Furthermore, analyzing my own choice of words in my first post,
it is evident that I’m not actually pointing a finger at anyone, and I’m actually submitting that without further evidence we cannot know who is to blame. If I was implying anything, then it was that supplying actual evidence regarding the incident would help us understand what truly occurred.
