I wouldn't aim to condemn him but I sure wouldn't wanna hang with him, neither. There's a time and a place for everything, we learn that along the way in life. I am asexual but it is one thing that helps define me, not the only thing that defines me or which I choose to extol over other things about me. That's where discretion comes in: there's some things I simply won't do in open public, wearing diapers and dressing up as a toddler girl isn't the only thing.
Forgive me for waxing OT-biblical here but even when it came to the Israeli temple, it wasn't a 100% open place; there was the General Assembly (where everyone could be), The Holy Place (where the devout and pious would be) and The Most Holy Place (where only the priesthood was allowed). We're the same way, we are like temples: most people know a fair amount about me, my close friends know some unknown things about me...and only a couple of real close friends know everything about me. That's how it's supposed to be. You wouldn't tell your sworn enemy about your diaper-wearing activity, right?
Discretion is the better part of valor. It all connects to Life, Liberty and the Pursuit of Happiness. For this guy in the news: IMHO, I don't think he's entirely happy...I think he's either resigned to the fate he created or in denial. I could be off in that assessment but I don't think entirely so. It's enough that I feel mixed (much less so than 20, 30 and 40 years ago) about loving to wear diapers and dress as a toddler girl, even as discrete as I am about it...but to wear it on my sleeve would probably see me in the past-tense eventually. That's not how I want to see this guy end up...but he does have some serious soul-searching to do if he wants to be at true peace with himself. Otherwise, people may view him as a lost-cause martyr-baby in a saggy diaper. We all live with the decisions we make and we all have the freedom to sit and reconsider them...while we're still here.
