Well it's not exactly retarded... it's just telling you the only English on offer is US English. It's more professional than less professional. US English = [beta] That's no lie that it's kinda 'beta'. Basically the early US settlers brought over English as it was during that period. Britain then wanted the US to update to modern English, but US settlers refused to do so. So there we have it! English as it was back in the 17th Century.
