English only, Please

Yeah, so got this in an email.  Talking about how we should "stick it" to America.  This should especially be worn in places of business where people of minor ethnicities work, such as McDonalds, Wal-Mart, different pharmacies, and tons of other places.  The ending thought of the message was, "Let's flood the USA with this one!!"

I could be wrong about this, but I'm pretty sure that in all those years of US history I had, they talked about how America was formed as a refuge for people of all backgrounds.  Yes, even people who weren't from Britain, which means they didn't speak English.  

Now, don't get me wrong--I'm completely aware that English is the official language of the US.  But this sentiment is clearly directed to Spanish-speaking people.  We speak volumes by having this mindset.  We say, "I'm better than you,"  "My country is better than your's,"  "I don't want you to be here,"  "Learn it or get out,"  "I want nothing to do with you."  Which is completely at odds with what our country represents:  freedom, opportunity, sanctuary, growth.  Why would we want to deny someone that?  By having this mindset, we loose the very values that the others are trying to attain!  It makes no sense!  

I wish I could speak Spanish, because it would help me greatly in explaing to a mother how often and how much medicine to give her child!  Is that unamerican??
