My ancestors came over here from Germany in 1849. They did it legally. They didn't get on welfare. They became Americans, learned English, joined the American culture, and obeyed the laws.
That is not what we are getting today. The Mexicans coming here have no intention of joining our culture. They have no intention of speaking English or of obeying our laws. They want to take back the entire American S. W. They even have a name for it: Aztlan
Arabs coming here also have no intention of joining our culture. They are quite adamant about conquering America in the name of Mohammed.
Irish, on the other hand... Europeans... even Japanese, and some Chinese DO want to join our culture.
I'm not against all immigration. (Just most) We are taking in WAY too many to assimilate, and if we don't assimilate them they WILL turn against us as a group. This leads to revolt. Which is where the L. A. Hispanic & Asian street gangs have positioned themselves. They see themselves as revolutionary gangsters in the mold of Poncho Villa. They romanticize their criminal activity as fighting "White Oppression". I say we're not oppressing them enough... we need to oppress them all the way back to Mexico!
