This CEO doesn't hate black people. He's not racist. He simply is against miscegenation.
Yeah, that doesn't work either.
> a view shared both culturally and legally by much of the USA.
Which isn't exactly relevant, the enlightenment of the majority is usually debatable and "much of the USA" isn't CEO of a company whose mission statement is "to promote openness, innovation & opportunity on the Web".
> It seems that those against this CEO consider gay marriage a civil right's issue.
How is it anything but a civil rights issue?
> But much of the USA doesn't agree, neither culturally nor legally.
I don't think so. They don't think the right should be provided, just as they did last time around, that didn't make civil rights issues "not civil rights".
