In my lifetime, lynching has been defended as necessary to protect the virtue and flower of Southern womanhood from the rapacious animal appetites of the subhuman African male. Today, commonly and to national audiences, Republicans have defended the position of the Minutemen, the Tea Party and the Arizona legislature on immigration issues as necessary to protect the sanctity of American national culture and the purity of the English language from the assaults of the Hispanic horde. Unless a Republican Party candidate publicly, loudly and repeatedly repudiates that position for the mean-spirited, un-American and bigoted drivel that it is, he or she isn't worth supporting for dog-catcher (Mexican catcher?).
America is all about paths to citizenship. Always has been. Always will be.
