I mean, yeah the comics are pretty much 50% "look how fucked up supes are in their day to day life" paired with gross out humor, 30% ultraviolence, 10% plot, and 10% feels.
They're all weird sex perverts because everyone rich and in powerful positions invariably is a sex pervert.
A lot of it is played for laughs or gross out humor though and just comes off childish but that's Garth Ennis in a nutshell.
I'm going to be absolutely fair, there were a few times, back when I was reading The Boys during its original run, where my eyes did roll a little bit and, though I was enjoying the series, I did find myself thinking, "Oh Garth, surely you're being a bit over-the-top now. That whole G-Men thing. That many people, involved in that kind of reprehensible shit, and it being an open secret and everyone knowing about it, but no one saying anything? That could never happen..."
And then Jimmy Saville died, and Operation Yewtree started kicking off, and it was revealed that practically everybody involved in showbusiness in the UK from the 1970s to the 1980s, possibly later, was part of a paedophile ring that included literal members of the sitting Conservative government, including a former Prime Minister, and that BBC children's television was basically a paedo's pick 'n' mix, where nonces could literally pick the kids they wanted to abuse backstage out of the crowd on Top of the Pops or whatever.
And then the story just died and everyone stopped talking about it. But I remember.
Then, a few years ago, Jeffery Epstein gets merked in prison, and the flightlogs come out, and lo and behold, it turns out to be exactly the same situation on the other side of the pond, just with a few details changed. Names get leaked. People freak out. "OMG, Steven fucking Hawking? Really?" There are memes galore.
For about a fortnight. Then everybody somehow forgot about it and moved onto the next thing.
And I just watched it all unfold and just kinda felt like Hughie reading through Butcher's files. So, no, I don't think it's unrealistic that every supe be some kind of deviant sex weirdo - if anything, I think Garth Ennis might have
underplayed how debauched and degenerate people in power and in the public eye are.
I also think that people criticising the comic for not having any positive supe characters (despite the fact that besides the obvious one, Starlight, there are actually several supes in the comic who are shown to be, if not entirely decent, then at the very least, normal) are entirely missing the point of the comic. If you want superheroes who are good and decent and just and always do the right thing, there's LITERALLY EVERY OTHER COMIC BOOK IN FUCKING EXISTENCE.
