Hate to break it to you, but words do hurt people and you’re not special because you can repress the feelings.
Or you literally don’t have them and are a sociopath.
But they do affect you in some way, you’re just privileged/tone deaf enough to never have the right ones aimed at you.
Or you realise that the people insulting you are brain dead and not worth the energy is takes to process their sound waves.
When ive seen what makes them cheer, why would their opinion have any effect on me?
