Well, if your desire is seeing people breaking those chains rather than enjoyment of the collar being welded shut, I wouldn’t call it a toxic focus - quite the contrary. Personally, injustice and abuse - even taking into account the catharsis of it being overcome - angers me too much for it to be a favorite. My blood pressure is already driven high enough by real-life events without it creeping into my much needed escapism, but to each their own. :)
