In fairness he has not made any kind of statement, and there is no evidence that he has in anyway acted in any inappropriate way to any other human.
People can believe what they want, and asking somebody to wear an emblem, slogan etc. that clearly is contrary to a belief which they are allowed to have, then jumping on them when they say they don't want to do it is oppression, just as bad a bigotry.
There are billions of people around the world who believe their religion condemns homosexuality, quite honestly I am baffled that anyone believes in any religion and I find 99.9% of it ridiculous, but I will defend their right to that belief as wrong as I find it, just as strongly as I will defend your right to practice your sexuality without persecution or censure. If you are willing to write of Maz you are willing to write off half the population of the world and all the good that those people contain.
It has been handled poorly, it should have only ever been a voluntary thing for players or anybody else to wear anything which advertises a belief.
What somebody believes and how they treat people can be completely separate, until I hear that Maz has discriminated against an individual or group of people then I will not fault him, just to be clear he has not discriminated against anyone, he has refused to be proactive about something.
