Why what the NBA did was right and what Mozilla did was wrong

Ironically, I find myself in agreement with Andrew Sullivan on this. Even though Sullivan supports gay marriage and I do not, he clearly sees the relevant differences between the two situations:

“If an owner of a business makes baldly racist remarks urging public dissociation from an entire racial group, private sector sanctions – from the NBA or fans or sponsors – are “permissible.” They are always permissible in a free country. That’s why Brendan Eich is out of a job. The second question is whether what is permissible is proper or justified, and that will always depend on the specific case. I think it’s obviously appropriate in the Sterling case – because the remarks are horrifyingly racist. If Brendan Eich had made comments telling his friends to keep away from faggots, if he’d used any such terminology or had ever been shown to have discriminated against gays in the workplace or in his daily interactions, then his case would be very similar. But no such comments are in the public or private record, and there’s zero evidence that he ever acted in the workplace to harm gay employees. Au contraire, which is why gay Mozilla employees were divided about his ouster, with some supporting him. Sterling’s remarks, in contrast, reveal him to be a crude, foul bigot – which is why there is no division at all among African-Americans in the league – or beyond the league – about his fate.”
