Katherine Coble explains her opposition to English Only in this post. Here is an excerpt:
I don’t quite get this tea party version of America some people have, where we have to have dress codes and codes of conduct that limit the individuality and freedom of citizens. I don’t get this version of America where some people think the things they like and enjoy should become codified while the things other people like and enjoy should become illegal. “America” doesn’t mean “I should get to boss you around because I was here first/have more money.” “America” means that you get to enjoy the pursuit of happiness through most means.
