I don't know or care what journalism school you went to, but that's absolutely not the way news decisions are made, and if you gave that as a reason why you didn't report a story, you'd get fired. The fact is that what public figures do is news, regardless if they themselves admit it. Bill Clinton didn't admit the story of his incident with Monica Lewinsky, and there are many others.
That's an entirely different situation. On the one hand, you have a public figure who's attempting to make a very personal change in life. On the other hand, you have a sitting president committing an affair. One demands a modicum of respect. The other does not. Bruce Jenner being a woman is not rightfully public information until Bruce Jenner says so. Bill Clinton getting a BJ from an intern is rightfully public information on the spot (pun intended) because he's the publicly-elected chief executive of the country putting himself in a compromising position on several different levels. There is no comparison to be made there.
And he also said he's not gay. So no, this is not the same thing as being gay.
Way to completely miss the point.
