Tim Cook, in an op-ed for The Washington Post:
He's right: this isn't a religious issue. The bigots that enact these types of laws are hiding behind their religion and using that as a way to reinforce their bigotry. Without the veil of religion obscuring their true intent, they'd have no other motivation to do this; they would have to admit to themselves and the rest of the world that they're just prejudiced assholes. Remember that these are the same types of people that would have made the same arguments about racial segregation.
It speaks a lot of Tim Cook's character to publicly stand out on this issue. Since I worked at Apple, I've known it to be an extremely inclusive company. Tim Cook's Apple is a company that preaches inclusion not just to those lucky enough to join the ranks, but to the entire world. Inclusion is becoming as much a part of their external branding as anything else, and it's a brave, bold move for the CEO of the most valuable company in the world to speak out so decisively on this. We need more like him to follow suit.
The world needs to know that any type of discrimination is not right, it's not acceptable for a civilized culture, and it most certainly is not Christian. Anyone who argues otherwise is not a person worth knowing; it should be made clear that their behavior is abhorrent, and that their insistence to cling to their bigotry is worthy of nothing but shame.
