Dobson never knew how to declare victory and just get on with life. Like, once outed as CattyN, he could have just owned it, neutralizing easily two thirds of the hell that came his way. Sure, he'd still be called a hypocrite and a perv, but he'd not be as bad off as he got by sperging about it.
I'm still not 100% convinced he was too much into that fetish. I'm pretty sure he liked it, yeah, but mostly I think he was just looking for an under-served audience to glom on to. It fits the pattern of his life, with everything from Doctor Who, to Star Trek, to Korra, to Ladybug, to that podcast, you name it. He was always doing that, thinking he'd be the big fish in a little pond. He'd bumble in to any kind of fandom he thought he could become a big wheel in just by drawing his crappy comics, maybe even be given some kind of status as the "official" cartoonist of said fandom (again, like with that podcast).
Imagine how far Dobson might have gone, even if his art never improved one iota, if he just wasn't such an asshole. He fired off all the torpedoes in the Navy at his "tolls" and "haters," but only wound up sinking himself.
