You shouldn't feel bad about your own pedantry; the only people who complain about others' pedantry are people whose egos can't ever just accept the fact that they're wrong, they have to feel better about themselves by belittling the other person as if somehow they're the asshole for actually knowing stuff. If anyone, without any sense of irony or humour, accuses you of being pedantic make sure they fully understand just how much of a cunt they are before you walk away smugly, secure in the knowledge that you're in the right and that you're better than them simply by the virtue of actually giving a fuck about truth and facts. Accuracy matters. Try telling someone who mixes chemical explosives for a living, or a nurse giving our medications, that accuracy doesn't matter. Ok, calling Frankenstein's monster Frankenstein might not result in death but it's the principle that counts lol.
