Petition here. Note you do not need to be Jewish to sign this petition. Excerpt:

'Within Judaism, the Brit Milah, a ritual circumcision performed on the eighth day of life, is considered a central rite.

Reform Judaism, progressive in many other ways, has yet to re-evaluate this practice, in spite of clearly compelling evidence of its medical and ethical shortcomings.

We therefore petition the leadership of the Union for Reform Judaism and the Central Conference of American Rabbis, as principals of the reform Judaism movement within the United States of America, to recognize these shortcomings, and to sanction alternative religious ceremonies that are spiritually relevant but also medically and ethically responsible.'
