The goal is humanizing gay people. That's the importance of coming out. You need to come out to people you can trust and people whose opinions you can change and you as a tiny, unimportant person probably need to be careful. At this point Tim Cook coming out isn't very important or brave. Ellen Page, maybe, because she's not a very stereotypical lesbian and is even a bit wholesome, girl next door. The Cook story just shows that it's less and less of a big deal every time this happens with a public figure. Every time some random person comes out it could be 1000 times braver, and even more important, than a celebrity, it's just not news. There's no angle for public interest or spectacle and there doesn't need to be for little courageous acts to be important.
