Will Americans tolerate the Hispanic take over?

I know many people who complain about immigration and are racist towards Hispanics in general. statistic wise its pretty much known fact they will be the majority in time in terms of population and language. You think Americans are gonna custom themselves tot his or will they have a cultural clash because not to be rude, some one i know thinks Hispanics come here to expect people to imilate with their culture and they get all angry when you don't. Even Arnold Swarchznagger said that Hispanics have to learn to come here and imilate with American culture, just like if i went to Japan i wouldn't be all"America man F yeah" no i would do the proper thing and imilate with the set culture and take it as a learning experience so what do you think?
