Could ignorance of the english language be the reason?

I have noticed that whenever people can't carry a conversation because of their limited vocabulary they get angry & lash out at the other person in desperation to the point that they call the other person names. Perhaps if the illegals made more of an effort to learn to speak english so that they can be able to carry dilogue there might be better understanding of where we as Americans stand.When I convers with legal or illegal immigrants in spanish I can bring even the hardest of them realize our dilema & we come to agreement on verious issues. There is of course the ones that are so narrow minded that they can see through a keyhole with both eyes at the same time. But what we have here basically is a [failure to cmmunicate]. Maybe what we need is good pro & con debates, maybe than they will realize it's not a race issue but a legal issue.
