Michael Sam, the first openly gay player to be drafted by the NFL, on Sunday penned an op-ed for the Columbia Daily Tribune against a so-called religious liberty bill in Missouri.

Senate Joint Resolution 39 (SJR 39) would amend the Missouri Constitution to protect organizations and individuals opposed to the Supreme Court's June, 2015 finding that gay and lesbian couples have a constitutional right to marry.

The bill's text states that Missouri “shall not impose a penalty on an individual who declines either to be a participant in a marriage or wedding ceremony or to provide goods or services of expressional or artistic creation for such a marriage or ceremony or an ensuing celebration thereof, because of a sincerely held religious belief concerning marriage between two persons of the same sex.”

An individual is defined as “a natural person or a closely held commercial entity owned by a natural person or persons.”

Sam said that he was speaking as an athlete who grew up in a Christian home.

“[T]wo things were always made clear to me: First, treat every person, every team, every competitor with respect. Second, everyone should have an equal shot and start on an equal playing field. What Missouri lawmakers are attempting to do, however, is push an anti-LGBT resolution that ensures LGBT people start at a loss,” Sam wrote.

SJR 39, Sam added, “would amend our state's constitution to allow businesses to legally refuse to provide services to same-sex couples. … SJR 39 is the opposite of respect, and it's the opposite of equality. It does not reflect the Missouri I know.”
