If you owned a business and wanted to attack customers who spoke Spanish, you wouldn't think it was smart to know some Spanish yourself?
Why would one want to "attack" someone who spoke Spanish? Most of us rational types don't "attack" someone who speaks a language other than our own. I agree we should all speak English in this country, but please, there is no reason to attack others who don't speak our language. You are just a little on the radical side aren't you?
