Dear Kociamama :)
dDoes love of English mean that people think that English nation and culture in general is superior?:) (It's a question for you and for other people who would be kind enough to join, not a challenge or something) As far as I am concerned, I think that GB (or any other country) is neither superior nor inferior to any other state. Of course, my strong feelings to the language are inseparably connected with urge to know about the culture as much as possible ! That's why I love English literature (especially Novel and Drama ) , history (especially Tudor times), geography.. and many other factors, which I failed to mention, but which are crucial to form the culture of a particular country.
I agree that all the people claiming they are proficient/advanced/ intermediate may as well write in English. After all, this website is created for people who'd like to brush up their language, and get to know more about the culture of English speaking countries, not necessarily England, but also Scotland, Wales, Ireland, New Zealand, Australia, USA.. Malta :D and many others :)
Cheers !! :)
