Put those signs in the hands of white people in red ball caps, and tell me how that makes you feel.
Conservatives don't demonize Hispanics. We call out those who break laws, but we are completely supportive of those who follow laws. We want them to come enjoy all that America has to offer.
By contrast, liberals only want illegals they can manipulate with fear into slave labor.
And don't get me started on the demonization of white people, men in particular.
