Perhaps you need to talk to those who are truly inflaming this issue...
...you know, the ones you are defending.
LEt me say this. I have no clue how it is in LA. However, My wife is from Mexican American descent. Through marriage I have a few relatives that couldbe classifyed as anchor babies. What you are seeing on the street does not represent all Mexican American thought. There are many divergent opinions out there in that ethnic community. It gets really confusing when these symbols such as the Mexican flag get used. To my wife its a symbol of ethnic pride and thats it. However, I know there are radical groups out there that have some reclaimation radical agenda that it has different symbolism for them.
I am just saying that the pictures of some these rallies can be quite misleading because it paints a picture that a "whole group" thinks a certain way.
