To be fair to Raul, he appears to have been referring to an organization, not the langauge itself.

It's certainly fair to point that out, but it doesn't make Yzaguirre's comparison any more valid (or any less racist).

The organization's board includes such noted "Klansmen" types as George Gilder, Nathan Glazer, two Hispanics (the organization's Chairman Mauro E. Mujica plus Alex Olmedo) and California governor Arnold Schwarzenegger.

The group's stated mission:

To help improve the teaching of English to immigrants, to allow them to enjoy the economic opportunities available in this country.

To study language policy and its effects around the world, so we can apply the lessons learned through the experiences of other countries to the United States.

To raise public awareness through the media about the importance of our common language

I think saying it's like the Klan is despicable.

U.S. English was founded by S. I. Hiyakawa. (If you don't know who he is, you've missed a couple of years of education. - Not "you=eric", just "you=anybody.)
