I remember a piece I read in about 2003, writer for new Yorker or Slate or something was home for the holidays with her Japanese-American family. Her family, around the Christmas table was talking about the post 9-11 world, was saying the US should have tighter security and more restrictions on "Muslims" in the US, though admitting the vast majority of them were the same as other citizens.

The writer was horrified that her family--who had a grandfather in Manzanar at the table--was so ready to trod down the same road only a few decades later despite their firsthand experience in the US after Pearl harbor.

If those folks are so easily manipulated by propaganda, what hope does an average person have?
