Off politics for a bit - plagiarism is running rampant through our culture, and no one seems to care enough to do anything about it. As far back as high school, I was taught copying another's work (especially uncredited) was the worst crime intellectually you could commit. But that was in the seventies. Now, and in popular music particularly, the gloves are off. Rappers gleefully admit "biting" another rapper's work. Sampling is common place .
Lady Gaga (whom I like) admits to being influenced by Madonna, but I don't think you could say she was stealing from the Material Girl. But right now, there at least four ambiguously sexual, rail-thin, spooky chicks drinking Gaga's Little Monster Kool-Aid. The last BET Hip Hop Awards (which I am compelled to watch because of work) was three hours of the SAME SONG.
I only point this out to say blatant plagiarism is still criminal, but like popular culture, politics seem to have been given a free pass.
