intactivism (名詞):支持立法來禁止嬰兒割包皮的立場或主張。

For Chapin and other advocates at Intact America, even a discussion over whether the potential benefits of circumcision outweigh its risks is unwarranted. The organization, the largest group of "intactivists" in North America, sent a petition with 25,000 signatures to the CDC in May stating its opposition to any recommendation in favour of infant circumcision.

Perhaps it's easier for these so-called "intactivists" to get attention at the local level. Hey, City Hall spent months talking about Happy Meal toys so why not? Both the San Francisco and Santa Monica measures would make circumcising any male under the age of 18 illegal, even for religious reasons.
