Kevin Williamson in National Review Online:

Next week, fourth-grade students at Penn Valley Elementary School in the gilded Philadelphia suburb of Lower Merion will spend part of their school day watching and discussing a very clever piece of cinematic propaganda courtesy of organized homosexuality. The film is called That’s a Family!, and it is endorsed by the Human Rights Campaign along with other homosexual activist groups. 

... That’s a Family! is not about tolerance or treating people decently. It is about indoctrination, a fact that its enthusiasts make little attempt to hide. It lists among its endorsers such Democratic worthies as Senator Barbara Boxer, who declares that the film can be used to “break down” attitudes she finds disagreeable. Loret Peterson, a fourth-grade teacher in (of course) San Francisco, wrote that the film provides “a gentle starting point to reach elementary age children with a message of respect for all differences before biases become entrenched and the pressures of middle school set in. . . . We have the opportunity to take an active, moral approach to deflating the power of stereotypes by addressing them in the classroom.”

... There are no cease-fires in the culture wars, because the Left simply will not stop until it has achieved total conformity, which it pursues under the banners of “tolerance” and “diversity,” i.e., a virtue the Left does not possess and a condition the Left will not abide. The front runs through every corporate human-resources office, every college campus, every church, and the fourth-grade classroom at Penn Valley Elementary School, too.
