Is asking for THE British accent a Taboo?

I was reading random discussion forums on the Internet the other day and I found this (very old btw) one where someone asked the following question: Would it be possible to type in a British accent? In return, this person got really sarcastic and mean/funny comments like "there ain't such a thing as a 'British accent', you bloody fool" There is always controversy around British accents since it is indeed a very important issue for native speakers. Moreover, it was not the first time that I encountered this kind of reactions although this time it was on the Internet and not in real life. So, is asking for 'THE British accent' a taboo? I will try to explain why people get that nuts and sensitive with this subject.
