NEW YORK - In response to the continued controversy over the proposed Islamic community center, the American Civil Liberties Union (ACLU) and the New York Civil Liberties Union (NYCLU) will begin displaying an ad promoting religious freedom throughout the New York City transit system starting Sep. 20.

The ad asks, "Would there even be a controversy if this weren?t a mosque?" and features three images of the proposed Park51 community center with a Latin cross, a Star of David, and an Islamic crescent and star, respectively.

The ad declares, "In America, religious freedom knows no boundaries."
