I would feel the same way if he contributed a million dollars to something far more extreme, and I am not sure if it would carry any more or less weight if that extremity were suddenly as personal or close to home as is the matter of gay marriage. Some people do like to hide behind the concept that, if you're not gay then why are you having X, Y, Z opinion in this conversation; I wanted to throw it out there that, as a gay man that loves his boyfriend but also loves people's opinions and the right to have them, this seems like a damn shame.
Mozilla wasn't going to become some bastion for social counter-productivity just because one man, even in the CEO position, held a certain number of opinions; I trust him more than that, I trust Mozilla more than that, and I trust our ability to find out and handle that if it were indeed to happen.
