Is this Glenn Reynolds post a plea for more coverage of Tibet or less of Palestine?
GOOD QUESTION: Why Do Palestinians Get Much More Attention than Tibetans?
But, just perhaps, the Israel-Palestine question receives lots of coverage because it's a question, at root, of competing rights, not because the media has an incurably anti-Israeli bias or is, in this instance at any rate, acting in an especially hypocritical fashion.
The other answer, of course, is that readers, are much more interested in the Middle East than they are in China and Tibet and, consequently, this is just market forces at work. Shocking!
