I’m deliberately going back to it. I don’t know what’s wrong with me, but it’s like some sort of compulsion. I “forgot” my phone all day at work today, and when I came home, I ran to it and ran to this particularly nasty new one that bothers the most yet. Something must be wrong with me 😦. I was barely able to get out of bed this morning.
My completely uninformed take: You get a fight-or-flight (adrenaline or somesuch) rush when you encounter someone being truly vile like that. But by just reading some screed on your phone, you just get the hormonal rush without any real danger to your person. IMO it’s like watching a horror movie. You don’t actually like murder but OMG did you see that disembowelment?!? You may not actually consciously enjoy the feeling–in fact you may consciously hate it–but your body/subconscious may crave the hormonal stimulation derived from it nevertheless.
As for solutions: all I see are OCD medication and substitution. OCD medication sounds like it’s already being worked on (lots of trial and error I’m afraid), but you could try substitution. Find something else that gives you the same rush. Honestly I’d try lots of exercise first–if you can manage to get your hormonal fix via runner’s highs (or swimming or biking or whatnot), that’s way better on you emotionally and physically than these hateful screeds.
EDIT: I guess I should also mention that many people with OCD self-medicate with enormous amounts of stimulants (“A Plague of Tics” by David Sedaris comes to mind–his “cure” was chain smoking). It’s not really the recommended path, but if you just gave up coffee and/or cigarettes and now your OCD is acting up, well… That said, depending on the person caffeine and nicotine may not be strong enough stimulants, and then you have other reasons you should avoid the self-medication path (expensive/illegal/dangerous take your pick).
As for “something must be wrong with me”, I hope you can get to the point where this can be something you manage and channel, and not something you hate. Not to tie our situations too tightly together, but I did subtitle Star Wars in 38 languages, 36 of which are complete gibberish to me. It was definitely not done entirely out of the kindness of my own heart. By all reasonable measures, something must be wrong with me too. But I’ve reached a place in my life where I’m cool with that, and I hope you can reach a similar place yourself.
