The New York Civil Liberties Union says mosques and the people who worship there have been subject to negative stereotyping, official obstruction and hostile acts in recent years, and warned of more to come as the 10th anniversary of the 9/11 attacks is followed by a fierce election cycle..."The anti-mosque and anti-Muslim sentiment expressed in the opposition to Park51 was not an isolated incident," Lieberman said, hastening to add NYCLU recognizes the right of the mosque's opponents to speak out...NYCLU's report ranges from the international furor over Park51 to ugly but minor incidents such as the September 2010 vandalism of a mosque in the city of Hudson. It revisits several controversies in which public officials or community members have attempted to block the construction or expansion of mosques out of what Lieberman termed "an undifferentiated fear and distrust of their Muslim neighbors."
