Everywhere else in the world with the exception of prudish north america, "Cunt" is just a synonym for asshole; regardless of gender.

That may not be where the word started, but that's where it currently is in modern usage.

now you want to start calling people "edgelords" lol. maybe it's time to look at your own embarrassing, disgraceful behaviour and consider the possibility that you're a gigantic flapping twat

Look, I don't mean to antagonize you but you're looking at it in a very American-centric (and quasi-chauvinistic) way.

In other countries the c-word doesn't have the same connotation as in the US. You are assuming American culture, and its concepts, are universal. They're not.

There's nothing inherently wrong in the c-word and the n-word, but it's the context where those words got to be used that made them so repugnant. Since the n-word was mostly a US thing, its taboo meaning passed over to all variants of English. The c-word though, was already used in other variants and didn't have the same bad connotation it does in the US. So it kept being used in a different way.

Trying to force the American meaning on other English speakers comes, at best, as ignorant and, at worst, chauvinistic. I don't think you have bad intentions since you clearly don't understand how a word can have very different meanings in different cultures. But now you know.
