it is irrelevant if it should be a big deal or not
noone would want this to be a big deal, but it is a huge step for anyone who is gay and in sports, especially professional sports.
i dont even know why you'd want to make the comparsion of the progress with gay equality and black equality, they're not the same. and trying to use it to belittle the progress in gay equality is just dumb.
the fact that other players of NBA would make ignorant statements minutes after the news, statements which had to be backed up by their team's PR management to save their asses, should be enough for you to understand that the culture in sports is different.
naw, it's not irrelevant if it's a big deal or not because i'm talkin' about the media's perspective. and the media routinely doesn't report on things that aren't a big deal. i don't think this should be much bigger than a single day announcement (perhaps that's all this really is tbh) and if that is the case then yea it isn't a big deal. it should just boil down to, "ah cool, good for him. glad he feels comfortable enough to share that." and that's about it.
maybe it'd be something huge if he was the first professional athlete to come out but he isn't so it's relatively minor progress (albeit still progress i suppose). i get the feeling you don't actually know of any other professional athletes that have come out within the past year given your response, which is straight (lol) but maybe do a little research before you start pushin an agenda i guess
