The problem with those 'worst people on the internet' is that they were pointing out that Kyle had been busy lying - libeling, really - people like Jesse Singal, working up hate mobs towards anyone he disagreed with, and ignoring facts that didn't fit his preferred narrative rather than being an actual journalist. He even admitted to some of these behaviours while claiming to have 'been in a dark place', though I'm guessing that tweet, while preserved in this thread somewhere, has been long-deleted now.
So it's not so much other people taking apart his life as it is Kyle's own actions of deceit and malice getting exposed to the world, with personal and professional consequences. Of course, you frame it like that, and it's much less sympathetic, isn't it.
To be fair to Kyle, he tells a few hard truths in this piece
Having read a few of his pieces, he's not that bad a journalist. Even on troon issues, where he's actively pushing an agenda, there are not only numerous troons worse than him but he has allowed room for a slight bit of nuance. Rarely, often caveated, but by even acknowledging that sometimes a trans person can be in the wrong and not everyone who has a problem with a single trans person is a Nazi TERF who wants to murder them all - that puts him above quite a few journalists, even normal ones.
And he even appears to have decent journalistic instincts at times, in the paragraphs before everything comes back to being about troonism. It's funny, if he hadn't trooned out he might have been half-decent, but being a half-decent journalist means fuck-all nowadays, so the only reason he ever got jobs was by being a zealous troon hack who reinforced a narrative rather than actually tried to spot the truth. It's the problem of the diversity hire: that diversity is all your employers, and therefore you, are allowed to produce content about, and you're expected to stagnate in the job without getting any better because there are no expectations for you to have skills, only represent a 'voice'.
Kyle, for his many, many faults, is not a Fire, Jake Alley, Sapphixy or Lou Gagliardi, to name just a few. That's an incredibly low bar to clear, but not being rock-bottom is an achievement for a cow like Kyle. He also manages to be at least slightly less insufferable than Grace Lavery, Laura Kate Dale and Ana Valens, which again - incredibly low bar, but still something.
The main problem, of course, is that troons who have that glimmer of self-awareness are the ones more likely to off themselves once they realise what they've done to their lives. It's those completely divorced from reality, like all the other troons listed, who suicide-bait like it's their job but are too narcissistic to do it. Having squandered a talent gives you something to mourn, while fucking up an already fucked-up life means you don't know what you're missing. I don't feel bad for Kyle because he chose to become a waste of space, and a right asshole while he was at it. But his delusions appear to be skating on ever-thinner ice, and it won't be pretty when it breaks.
