Another state constitutional ban on same-sex marriage has been struck down. A federal judge ruled today that Oklahoma's ban on same-sex marriage violates the guarantee of equal protection in the U.S. Constitution, USA Today reports. The ban, the judge reasoned is "'an arbitrary, irrational exclusion of just one class of Oklahoma citizens from a governmental benefit,"' USA Today further reports. The ruling, unlike a similar one in Utah, was stayed for the inevitable appeal.
