I don't feel bad stooping to their level on this. Moral victory is pretty meaningless in the end, especially in a situation like this. It's really just cathartic.
Not even that if it's as obvious that they genuinely couldn't care less about your moral victory and are proceeding to keep being subhuman slime with zero sense of consequence for it.
You can be a better man if you want, i'm not wasting social niceties on someone who took a fat dump on the social contract and told
me to eat up. And that is my choice to make.
