Have you ever been to Chinatown?
Sure. Quaint, isolated, most everyone speaks English as well as Chinese.
So far, we don't have the Chinese taking over large parts of our country and requiring Mandarin billboards and Chinese Wall-Marts.
At the moment, we have large waves of people entering illegally and demanding separation in language and culture.
Businesses that facilitate that process betray their country and should be boycotted.
