Others’ humanity is negotiable to me because I only have to engage with violence in the abstract. In reality I avoid any and all confrontation no matter how egregious the fault. My friends and family don’t know the amount of unprocessed rage I store in my body. I am a very healthy and well balanced person who is good to be around.
Just call people you don't like "NPCs" and the implication is that human rights don't apply to them. It works for both creepy incel-pandering isekai treats and for the political views of billionaire bazingas that also enjoy creepy incel-pandering isekai treats!
