What really bugs me, though, are those RACISTS who somehow imply society needs one primary language in order to function. As though we need to understand each other. Please. I bet those racist jerks think language segregation creates a barrier of poverty for segments of society based on the language they speak. Give me a break. Just look at the nordic countries and the amazing success they've had with their language diversity. Next they'll be saying it's up to the immigrants to assimilate to the country they migrate to instead of the country's responsibility to bend over backwards to accommodate any possible immigrant it may possibly have in the entire world. It's called a MELTING pot, which means do things however you want regardless of the practical limitations of such (though there are none. I'm just saying practicality doesn't play a factor, your racism does.)
Hopefully one day the racism will end and every sign, book, tv show, movie, and business will accommodate every language on earth.
