Everyone is entitled to their opinion, but David Tyree, former NFL star and anti-marriage equality advocate, really should learn to think about what he’s actually saying before going on TV to repeat them. Otherwise he comes off as bigoted and uninformed.
By the way, I get really tired of the “gay marriage leads to polygamy” slippery slope argument. Assuming that the state wants to limit the number of people in a relationship, there’s no reason they cannot limit the number of people who sign a contract. They just shouldn’t do it based on an innate quality — such as being gay (or black, for that matter) — of the person signing that contract.
