It occurred to me after reading this article about Elizabeth Dole's unbelievably offensive attacks against her competitor for a senate seat in North Carolina that prejudice is alive and well and still a-ok in the US. Of course, it is no longer socially acceptable to attack people for their gender or the color of their skin (at least not openly), but there is certainly lots of wiggle room for those who thrive on putting other people down to jack themselves up.
Who is it okay to revile?
Mexican immigrants (legal or otherwise)
Unmarried black parents
Southerners and others who are unfortunately accented
Feel free to add your own.
