A Kansas sperm donor who was ordered to pay child support for the baby he helped a lesbian couple conceive plans to fight back in court, and suggested he might be a victim of bias against same-sex parenting.

William Marotta told FoxNews.com he might never have agreed to provide sperm to Angela Bauer and her former partner, Jennifer Schreiner, had he known the legal morass that awaited him after responding to the women’s Craigslist ad for a donor in March 2009. The Kansas Department for Children and Families (DCF) recently filed a child support claim against Marotta after the couple filed for state assistance this year, leading the department to demand they provide the donor’s name so it could collect.
