If you heard the regular personality on NPR's "Here And Now" say that someone was openly gay, you would assume he was out.

That's where I learned it. I didn't know for a few weeks later that it was supposed to be a secret we didn't say.

I would wonder why I'd never heard it right from the only person qualified to say, find that he hadn't said it, and doubt the credibility of the person who reported it as true. But I also know what it's like to be afraid of being outed to people you're not out to, so maybe it's different if you don't have that fear.

I'd typically interpret "openly" as implying "out", though.
