I stumbled upon this non-profit organization http://www.houstonculture.org/index.html while googling the term "Treaty of Gaudaloupe signers". Though the home page looks both friendly and beneign another, more ominous agenda emerges when you go in and look around.

It begins:

A ghost from the past is haunting America. But this ghost is no phantasm -- it is the emergence of millions of Mexicans and Mexican Americans, descendants of the people who were dispossessed of their land and denied their birthright in the southwestern United States, who are growing in power and hungering for justice.
And this is simply the first paragraph of a scathing, 3 part series (complete with blatant, revisionist history).

Everyone, to the person, in charge of granting 501(c)(3) status, needs to be FIRED!
