In federal court Wednesday, evidence in the case targeted a proponent of Proposition 8 who warned voters in a letter during the 2008 campaign that gay rights activists would try to legalize sex with children if same-sex couples had the right to wed.

San Francisco resident Hak-Shing William Tam, a defendant in the lawsuit, discussed the letter sent to Chinese-Americans church groups during a legal deposition taped last month.

"On their agenda list is: legalize having sex with children," states the letter, which also cautioned that "other states would fall into Satan's hands" if gays weren't stopped from marrying in California.
