Remember I reported back in April 2007 about YouTube was banned in Thailand. In March of last year, the similar case happened in Turkey where there were several videos that insulted the founder of modern Turkey, Mustafa Kemal Ataturk, which is a crime under Turkish law.
Recently New York Times has the article about Google, who owns YouTube, and the censorship. Where is the line between free-speech and hate-speech ? America exercises the freedom of speech, but not in many countries. I believe in a certain level of freedom, as long as doesn't harm anyone nor against the law (of other countries.)
