They are either kids or people who just dont speak any foreign languages or both combined into one. Honestly if you look at the average american it's not much different. They don't know **** about other countrys but their own and except for english and some spanish they don't know any other languages. Ofcourse not every 'Murican is like that but there's plenty who are like that, just like there is plenty of spanish/indo's or honestly any other country.... Just because this is an english game (okay and spanish/german but still english is the main lang) you notice the language barrier from people who come from countrys that are not english based.
Might be generalizing too much but that's how I've experienced the rohan community so far.
