Actually, the first thing that jumped to mind was the relatively recent closing of Catholic adoption agencies in several states, because the church decided their charity services were less valuable than their ability to discriminate against homosexuals. Most recently, the Catholic church shut down their adoption and foster care services in Illinois, because the state mandated that same-sex couples be provided equal consideration as adoptive or foster parents.
