This document summarizes and provides arguments in support of Illinois House Bill 0110, known as the Religious Freedom and Marriage Fairness Act. The bill would legalize same-sex marriage in Illinois while protecting religious organizations' right not to perform or recognize such marriages. The document argues that denying same-sex couples equal marriage rights violates principles of equal protection and cannot withstand strict scrutiny review. It also argues that allowing same-sex marriage does not harm traditional marriage or children, and respects the separation of church and state mandated by the US and Illinois constitutions.
