The movement has been especially successful at limiting free speech in the guise of protecting religious freedom, as the article notes
What has the Human Rights Council done about this? On March 28, 2008, the Council actually undermined its own ability to protect free speech. An amendment to a resolution on freedom of expression (passed 27 to 15 with three abstentions) now requires the U.N. Special Rapporteur on Freedom of Expression to “report on instances in which the abuse of the right of freedom of expression constitutes an act of racial or religious discrimination.” Instead of traveling the world in search of instances in which free speech is unjustly limited, the Rapporteur will now do just the opposite, in an effort to police “abusive” speech. The protector has become the oppressor. The Council failed to note that Muslims (and all citizens) are already protected against discrimination and defamatory speech by Article 19 of the International Covenant on Civil and Political Rights, and reasonable limits to free speech were already referred to in the preamble to the March 28 resolution. Further, concerns for freedom of religion are already reported by the Special Rapporteur for Freedom of Religion.Ed Brayton points out that the "Islamic Human Rights" that advocates are promoting as complimentary to the UDHR is in fact theocracy, something explicitly rejected by the UDHR.
With such protections already in place, this amendment’s only effect is the undermining of what little ability the HRC has to safeguard free expression around the world.
