No, I think they were just dumb as fuck. He went on "Ellen" and
tried to give more context, and didn't help himself, particularly. I think it's not a big deal, but what he said in that first interview was just a mishmash of nonsense. Actors' private lives aren't "mysteries", especially when they're married.
In some kind of ideal state, though, they very well might be. A lot of the better actors are, in fact, known for not being particularly forthcoming about their private lives.
In a few cases, their private lives can be downright distracting. I didn't really care Tom Cruise was a Scientologist for most of his career, but when he made acting like an idiot in public constantly about it the centerpiece of his public persona, I could no longer take anything he was in seriously.
Similarly, Woody Allen's creepy private life, which turned out way worse than previously thought, ends up distracting from his movies, though perhaps this is because he usually basically plays himself. When you know he is a gigantic creep, it is impossible to take his neurotic but harmless nebbish protagonist as anything but an unreliable narrator, making movies like Manhattan retroactively much more creepy than they used to be.
Obviously, it's not always possible in a celebrity-obsessed society to have that, and it doesn't automatically wreck a performance to know, for instance, that Rock Hudson really didn't want to bone Doris Day.
It was pretty awkwardly expressed, but wasn't homophobic. If there was a single thing, though, that was definitely true in that mishmash, it is that actors have had their careers suffer, even in recent years, because they came out.
