I spoke poorly saying "Conservatives hate Hispanics.."     I should have said some racist conservatives hate Hispanics.   It's wrong to say thats true of all conservatives and I apologize.   

My conservative church spent significant resources or Mexican missions, both to build homes, but just as much to let the young see the Mexican people in a positive relationship.   My daughters and I found the poverty shocking, but were warmed by the reception and interaction with the neighborhood children.   The same church did missions in Chicago, Milwaukee, Indian reservations, Memphis.  The goal is the same, to recognize equality of being God's children and volunteering for acts of compassion that reflect Jesus character.

A significant minority(?) of folks do not want the influence of Mexican culture to mix into their communities.   That's  a reality and would exist if every immigrant had entered legally.     It's a bias of race found across all political, religious, or economic strata.
