The Human Rights Council and defamation of religion

hrc defamationYesterday I claimed that governments do not take the Human Rights Council seriously. The most famous example is the effort by that body to advance a right against “defamation of religion.” In 2010, a resolution supporting this right was passed by a vote of 20 to 17 with 8 abstentions. (There have been other votes in favor as well, both in the Human Rights Council and the General Assembly.) The graph showing the breakdown of votes by Freedom House score is above. The question for international lawyers is whether western governments like that of the United States are required to recognize a right against defamation of religion because a bunch of authoritarian countries think it should. If not, how exactly should we understand the legal status of the Human Rights Council?
