Keyboard activists with accounts at Amazon.com can vote for reviews they like. Here's some, ahem, opportunities I spotted while browsing around over there.

There's a review of the book "Let Them In: The Case for Open Borders" that could use some more Most Helpful votes. The review is titled "Suspension of disbelief required"

Most of the votes on reviews of Bill Ong Hing's book "Deporting Our Souls: Values, Morality, and Immigration Policy" seem to from his family and friends. Your vote for the "Compassion without justice" review as Most Helpful would add some balance.

Also, not one of the reviews of the movie "The Visitor" complains of the poor logic of the climactic scene, the one where the illegal says "I've done nothing wrong" and the American fails to say "You came here without permission". Someone needs to write a review that makes this point.
