There has always been 'bigotry' and 'prejudice;' it's human nature to have an us against them mentality and when the long-established see new, illegal, arrivals getting preferential treatment, then there is naturally going to be resentment and when that resentment is not placated, then it festers into anger and hatred as government takes and redistributes wealth to welcome in the invaders.
Our legal minority citizens dreaming of attaining middle-class status are thus squeezed out of the job market and robbed of opportunity by a group of people who only want the opportunity to take wealth and send it home looking towards the day when they can return home and retire only to send their sons and daughters over the open border to take their places...
A barrio of the illegals soon turns the homes of the struggling legals into barrio residents too, even though they are the ones who have assimilated. They want homes and family here and that takes decent wages, but the economic reality of importing cheap labor (hell we don't even have to import it, just advertise sanctuary and benefits and they will come) prevents their upward mobility which is why so many legal Hispanics are increasingly in favor of physical barriers and limiting the influx of of economic thieves.
Yes, there were two posters here recently, who identified themselves as Hispanics.
They both said that most people from the Hispanic community respect Catholic Religion, even if they no longer practice it (note that many White posters here bash Christianity because they see it as a symbol of White oppression), and both were for the Wall.
And I've seen other Hispanics (two Dreamers included) saying similar things on TV
